/**
* The response row. An alert dialog exists to be answered, so its buttons are anatomy rather
* than content — the one part `Dialog` deliberately does not ship, because a dialog's footer is
* whatever the consumer composes and an alert dialog's is always the same two choices.
*
* One layout at every width, because that is the convention for a `prompt` generally rather than
* a rule about alert dialogs: its buttons span the surface, one full width or two at even halves.
* A right-aligned pair sized to its labels was tried first and is what the designs do not do.
*
* A GRID rather than a flex row, and that is what makes both cases the same declaration. Filling
* the row needs `flex: 1` on each CHILD, which a parent cannot set — StyleX has no child
* selector, and reaching into the children would mean every call site remembering to pass
* something. `grid-auto-flow: column` with `grid-auto-columns: 1fr` puts it on the container
* instead: every button takes an equal share of the row, so one fills it and two split it, with
* no branch and nothing for a third to break.

fuggin opus.

All these styles are more comments than style. I kinda want to strip them out, but also maybe they're useful context for future agents editing 🤷

any thoughts?

almost wonder if this should just live in Dialog since we'll use in on other prompt sized dialogs for inputs that will have the same styled actions 🤔 . easy swap if so

Yeah I could see this living in Dialog since it isn't specific to Alert dialog

📝 Walkthrough

Walkthrough

Adds the Mosaic AlertDialog component with compound parts, controlled and uncontrolled state, focus management, dismissal handling, accessibility checks, and styled actions. Extends Dialog for compound-part naming and reusable content. Adds tests, public exports, Storybook stories, MDX documentation, registry integration, and a changeset.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk:🔵 Low · up to a26f7

The new public AlertDialog may be published without appearing in the intended release version or changelog. The PR is otherwise mergeable with explicit owner follow-up on the release entry.

@maxyinger
feat(ui): add Mosaic AlertDialog
d4b461c
A Dialog that interrupts to ask for a decision and waits for one. Base UI's
shape: the same parts as Dialog, with the three props that would let it stop
being an alert dialog removed rather than defaulted — `role` is `alertdialog`,
`closedBy` is `closerequest`, `size` is `prompt`. Everything else is Dialog's
own component rather than a wrapper around it, so there is one implementation
of each and no way for the two to drift.
No `CloseButton` part, for the same reason an outside press cannot dismiss it:
a corner X is a way out without answering.
`AlertDialog.Actions` is the one addition — the response row, which is anatomy
here in a way a dialog's footer is not. A grid rather than a flex row, because
the phone layout is a property on the container instead of something every
button has to be told: `grid-auto-columns` is `1fr` under the sheet band, so
the buttons split the row and span it, and `auto` above it, where the tracks
size to their labels and sit at the inline end. Full-width beats a right-aligned
pair floating against one edge of a screen-wide sheet.
The cancel goes first, which makes it the first tabbable element and therefore
what the alert opens focused on — the least destructive choice, with no
`initialFocus` plumbing, and with the keyboard order agreeing with the screen.
Title and Description are both required, and both warn in development when
missing: an alert dialog's description is announced with its name at the moment
it interrupts, so without one the user is choosing between "Cancel" and "Delete"
with nothing saying what is being deleted. The existing name warning skipped any
role but `dialog`, which would have made it silently inert here, and it now
names the component it is complaining about instead of always saying "Dialog".
@maxyinger
feat(ui): split a prompt's actions evenly at every width
e71dea8
The designs give every `prompt` the same footer, alert dialogs included: one
full-width button, or two at even halves with a 0.75rem gap. Not a pair sized to
their labels against the inline end, which is what this shipped as.
So the media branch goes, and the row gets shorter rather than longer:
`grid-auto-columns: 1fr` unconditionally already means one button fills the row
and two split it, with nothing to switch on at 48rem and no edge case waiting for
a third. The phone layout was this all along — it is now simply the layout.

 /**
 * The response row. An alert dialog exists to be answered, so its buttons are anatomy rather
 * than content — the one part `Dialog` deliberately does not ship, because a dialog's footer is
 * whatever the consumer composes and an alert dialog's is always the same two choices.
 *
 * One layout at every width, because that is the convention for a `prompt` generally rather than
 * a rule about alert dialogs: its buttons span the surface, one full width or two at even halves.
 * A right-aligned pair sized to its labels was tried first and is what the designs do not do.
 *
 * A GRID rather than a flex row, and that is what makes both cases the same declaration. Filling
 * the row needs `flex: 1` on each CHILD, which a parent cannot set — StyleX has no child
 * selector, and reaching into the children would mean every call site remembering to pass
 * something. `grid-auto-flow: column` with `grid-auto-columns: 1fr` puts it on the container
 * instead: every button takes an equal share of the row, so one fills it and two split it, with
 * no branch and nothing for a third to break.

fuggin opus.
All these styles are more comments than style. I kinda want to strip them out, but also maybe they're useful context for future agents editing 🤷
any thoughts?

almost wonder if this should just live in Dialog since we'll use in on other prompt sized dialogs for inputs that will have the same styled actions 🤔 . easy swap if so

and move details about role, outside-press dismissal, sizing, and shared
behavior to the relevant later sections.
- Around line 125-132: Reorder the AlertDialog documentation sections to follow
the compound-component sequence: Example, Usage, Parts, then Styling. Change the
“Examples” heading to the existing singular “Example” section and place
“Confirming a discard” beneath it before “Usage,” keeping the Story example
unchanged.

@maxyinger
feat(ui): add Mosaic AlertDialog
d4b461c
A Dialog that interrupts to ask for a decision and waits for one. Base UI's
shape: the same parts as Dialog, with the three props that would let it stop
being an alert dialog removed rather than defaulted — `role` is `alertdialog`,
`closedBy` is `closerequest`, `size` is `prompt`. Everything else is Dialog's
own component rather than a wrapper around it, so there is one implementation
of each and no way for the two to drift.
No `CloseButton` part, for the same reason an outside press cannot dismiss it:
a corner X is a way out without answering.
`AlertDialog.Actions` is the one addition — the response row, which is anatomy
here in a way a dialog's footer is not. A grid rather than a flex row, because
the phone layout is a property on the container instead of something every
button has to be told: `grid-auto-columns` is `1fr` under the sheet band, so
the buttons split the row and span it, and `auto` above it, where the tracks
size to their labels and sit at the inline end. Full-width beats a right-aligned
pair floating against one edge of a screen-wide sheet.
The cancel goes first, which makes it the first tabbable element and therefore
what the alert opens focused on — the least destructive choice, with no
`initialFocus` plumbing, and with the keyboard order agreeing with the screen.
Title and Description are both required, and both warn in development when
missing: an alert dialog's description is announced with its name at the moment
it interrupts, so without one the user is choosing between "Cancel" and "Delete"
with nothing saying what is being deleted. The existing name warning skipped any
role but `dialog`, which would have made it silently inert here, and it now
names the component it is complaining about instead of always saying "Dialog".
@maxyinger
feat(ui): split a prompt's actions evenly at every width
e71dea8
The designs give every `prompt` the same footer, alert dialogs included: one
full-width button, or two at even halves with a 0.75rem gap. Not a pair sized to
their labels against the inline end, which is what this shipped as.
So the media branch goes, and the row gets shorter rather than longer:
`grid-auto-columns: 1fr` unconditionally already means one button fills the row
and two split it, with nothing to switch on at 48rem and no edge case waiting for
a third. The phone layout was this all along — it is now simply the layout.

Pin the alertdialog role so a consumer prop cannot downgrade it, and bring the
docs page back to the compound archetype's section order.

 /**
 * The response row. An alert dialog exists to be answered, so its buttons are anatomy rather
 * than content — the one part `Dialog` deliberately does not ship, because a dialog's footer is
 * whatever the consumer composes and an alert dialog's is always the same two choices.
 *
 * One layout at every width, because that is the convention for a `prompt` generally rather than
 * a rule about alert dialogs: its buttons span the surface, one full width or two at even halves.
 * A right-aligned pair sized to its labels was tried first and is what the designs do not do.
 *
 * A GRID rather than a flex row, and that is what makes both cases the same declaration. Filling
 * the row needs `flex: 1` on each CHILD, which a parent cannot set — StyleX has no child
 * selector, and reaching into the children would mean every call site remembering to pass
 * something. `grid-auto-flow: column` with `grid-auto-columns: 1fr` puts it on the container
 * instead: every button takes an equal share of the row, so one fills it and two split it, with
 * no branch and nothing for a third to break.

fuggin opus.
All these styles are more comments than style. I kinda want to strip them out, but also maybe they're useful context for future agents editing 🤷
any thoughts?

almost wonder if this should just live in Dialog since we'll use in on other prompt sized dialogs for inputs that will have the same styled actions 🤔 . easy swap if so

and move details about role, outside-press dismissal, sizing, and shared
behavior to the relevant later sections.
- Around line 125-132: Reorder the AlertDialog documentation sections to follow
the compound-component sequence: Example, Usage, Parts, then Styling. Change the
“Examples” heading to the existing singular “Example” section and place
“Confirming a discard” beneath it before “Usage,” keeping the Story example
unchanged.

feat(ui): add Mosaic AlertDialog
d4b461c
A Dialog that interrupts to ask for a decision and waits for one. Base UI's
shape: the same parts as Dialog, with the three props that would let it stop
being an alert dialog removed rather than defaulted — `role` is `alertdialog`,
`closedBy` is `closerequest`, `size` is `prompt`. Everything else is Dialog's
own component rather than a wrapper around it, so there is one implementation
of each and no way for the two to drift.
No `CloseButton` part, for the same reason an outside press cannot dismiss it:
a corner X is a way out without answering.
`AlertDialog.Actions` is the one addition — the response row, which is anatomy
here in a way a dialog's footer is not. A grid rather than a flex row, because
the phone layout is a property on the container instead of something every
button has to be told: `grid-auto-columns` is `1fr` under the sheet band, so
the buttons split the row and span it, and `auto` above it, where the tracks
size to their labels and sit at the inline end. Full-width beats a right-aligned
pair floating against one edge of a screen-wide sheet.
The cancel goes first, which makes it the first tabbable element and therefore
what the alert opens focused on — the least destructive choice, with no
`initialFocus` plumbing, and with the keyboard order agreeing with the screen.
Title and Description are both required, and both warn in development when
missing: an alert dialog's description is announced with its name at the moment
it interrupts, so without one the user is choosing between "Cancel" and "Delete"
with nothing saying what is being deleted. The existing name warning skipped any
role but `dialog`, which would have made it silently inert here, and it now
names the component it is complaining about instead of always saying "Dialog".
@maxyinger
feat(ui): split a prompt's actions evenly at every width
e71dea8
The designs give every `prompt` the same footer, alert dialogs included: one
full-width button, or two at even halves with a 0.75rem gap. Not a pair sized to
their labels against the inline end, which is what this shipped as.
So the media branch goes, and the row gets shorter rather than longer:
`grid-auto-columns: 1fr` unconditionally already means one button fills the row
and two split it, with nothing to switch on at 48rem and no edge case waiting for
a third. The phone layout was this all along — it is now simply the layout.

Pin the alertdialog role so a consumer prop cannot downgrade it, and bring the

 /**
 * The response row. An alert dialog exists to be answered, so its buttons are anatomy rather
 * than content — the one part `Dialog` deliberately does not ship, because a dialog's footer is
 * whatever the consumer composes and an alert dialog's is always the same two choices.
 *
 * One layout at every width, because that is the convention for a `prompt` generally rather than
 * a rule about alert dialogs: its buttons span the surface, one full width or two at even halves.
 * A right-aligned pair sized to its labels was tried first and is what the designs do not do.
 *
 * A GRID rather than a flex row, and that is what makes both cases the same declaration. Filling
 * the row needs `flex: 1` on each CHILD, which a parent cannot set — StyleX has no child
 * selector, and reaching into the children would mean every call site remembering to pass
 * something. `grid-auto-flow: column` with `grid-auto-columns: 1fr` puts it on the container
 * instead: every button takes an equal share of the row, so one fills it and two split it, with
 * no branch and nothing for a third to break.

fuggin opus.
All these styles are more comments than style. I kinda want to strip them out, but also maybe they're useful context for future agents editing 🤷
any thoughts?

almost wonder if this should just live in Dialog since we'll use in on other prompt sized dialogs for inputs that will have the same styled actions 🤔 . easy swap if so

and move details about role, outside-press dismissal, sizing, and shared
behavior to the relevant later sections.
- Around line 125-132: Reorder the AlertDialog documentation sections to follow
the compound-component sequence: Example, Usage, Parts, then Styling. Change the
“Examples” heading to the existing singular “Example” section and place
“Confirming a discard” beneath it before “Usage,” keeping the Story example
unchanged.

@maxyinger
feat(ui): add Mosaic AlertDialog
d4b461c
A Dialog that interrupts to ask for a decision and waits for one. Base UI's
shape: the same parts as Dialog, with the three props that would let it stop
being an alert dialog removed rather than defaulted — `role` is `alertdialog`,
`closedBy` is `closerequest`, `size` is `prompt`. Everything else is Dialog's
own component rather than a wrapper around it, so there is one implementation
of each and no way for the two to drift.
No `CloseButton` part, for the same reason an outside press cannot dismiss it:
a corner X is a way out without answering.
`AlertDialog.Actions` is the one addition — the response row, which is anatomy
here in a way a dialog's footer is not. A grid rather than a flex row, because
the phone layout is a property on the container instead of something every
button has to be told: `grid-auto-columns` is `1fr` under the sheet band, so
the buttons split the row and span it, and `auto` above it, where the tracks
size to their labels and sit at the inline end. Full-width beats a right-aligned
pair floating against one edge of a screen-wide sheet.
The cancel goes first, which makes it the first tabbable element and therefore
what the alert opens focused on — the least destructive choice, with no
`initialFocus` plumbing, and with the keyboard order agreeing with the screen.
Title and Description are both required, and both warn in development when
missing: an alert dialog's description is announced with its name at the moment
it interrupts, so without one the user is choosing between "Cancel" and "Delete"
with nothing saying what is being deleted. The existing name warning skipped any
role but `dialog`, which would have made it silently inert here, and it now
names the component it is complaining about instead of always saying "Dialog".
@maxyinger
feat(ui): split a prompt's actions evenly at every width
e71dea8
The designs give every `prompt` the same footer, alert dialogs included: one
full-width button, or two at even halves with a 0.75rem gap. Not a pair sized to
their labels against the inline end, which is what this shipped as.
So the media branch goes, and the row gets shorter rather than longer:
`grid-auto-columns: 1fr` unconditionally already means one button fills the row
and two split it, with nothing to switch on at 48rem and no edge case waiting for
a third. The phone layout was this all along — it is now simply the layout.

Pin the alertdialog role so a consumer prop cannot downgrade it, and bring the

 /**
 * The response row. An alert dialog exists to be answered, so its buttons are anatomy rather
 * than content — the one part `Dialog` deliberately does not ship, because a dialog's footer is
 * whatever the consumer composes and an alert dialog's is always the same two choices.
 *
 * One layout at every width, because that is the convention for a `prompt` generally rather than
 * a rule about alert dialogs: its buttons span the surface, one full width or two at even halves.
 * A right-aligned pair sized to its labels was tried first and is what the designs do not do.
 *
 * A GRID rather than a flex row, and that is what makes both cases the same declaration. Filling
 * the row needs `flex: 1` on each CHILD, which a parent cannot set — StyleX has no child
 * selector, and reaching into the children would mean every call site remembering to pass
 * something. `grid-auto-flow: column` with `grid-auto-columns: 1fr` puts it on the container
 * instead: every button takes an equal share of the row, so one fills it and two split it, with
 * no branch and nothing for a third to break.

fuggin opus.
All these styles are more comments than style. I kinda want to strip them out, but also maybe they're useful context for future agents editing 🤷
any thoughts?

almost wonder if this should just live in Dialog since we'll use in on other prompt sized dialogs for inputs that will have the same styled actions 🤔 . easy swap if so

Yeah I could see this living in Dialog since it isn't specific to Alert dialog

describing the new Mosaic AlertDialog API.

present-tense paragraph. Retain only its purpose and distinction from Dialog,
and move details about role, outside-press dismissal, sizing, and shared
behavior to the relevant later sections.
- Around line 125-132: Reorder the AlertDialog documentation sections to follow
the compound-component sequence: Example, Usage, Parts, then Styling. Change the
“Examples” heading to the existing singular “Example” section and place
“Confirming a discard” beneath it before “Usage,” keeping the Story example
unchanged.

the additional comment around the referenced later lines. Leave the story
behavior unchanged; if a comment is necessary, replace it with a single terse

@maxyinger
feat(ui): add Mosaic AlertDialog
d4b461c
A Dialog that interrupts to ask for a decision and waits for one. Base UI's
shape: the same parts as Dialog, with the three props that would let it stop
being an alert dialog removed rather than defaulted — `role` is `alertdialog`,
`closedBy` is `closerequest`, `size` is `prompt`. Everything else is Dialog's
own component rather than a wrapper around it, so there is one implementation
of each and no way for the two to drift.
No `CloseButton` part, for the same reason an outside press cannot dismiss it:
a corner X is a way out without answering.
`AlertDialog.Actions` is the one addition — the response row, which is anatomy
here in a way a dialog's footer is not. A grid rather than a flex row, because
the phone layout is a property on the container instead of something every
button has to be told: `grid-auto-columns` is `1fr` under the sheet band, so
the buttons split the row and span it, and `auto` above it, where the tracks
size to their labels and sit at the inline end. Full-width beats a right-aligned
pair floating against one edge of a screen-wide sheet.
The cancel goes first, which makes it the first tabbable element and therefore
what the alert opens focused on — the least destructive choice, with no
`initialFocus` plumbing, and with the keyboard order agreeing with the screen.
Title and Description are both required, and both warn in development when
missing: an alert dialog's description is announced with its name at the moment
it interrupts, so without one the user is choosing between "Cancel" and "Delete"
with nothing saying what is being deleted. The existing name warning skipped any
role but `dialog`, which would have made it silently inert here, and it now
names the component it is complaining about instead of always saying "Dialog".
@maxyinger
feat(ui): split a prompt's actions evenly at every width
e71dea8
The designs give every `prompt` the same footer, alert dialogs included: one
full-width button, or two at even halves with a 0.75rem gap. Not a pair sized to
their labels against the inline end, which is what this shipped as.
So the media branch goes, and the row gets shorter rather than longer:
`grid-auto-columns: 1fr` unconditionally already means one button fills the row
and two split it, with nothing to switch on at 48rem and no edge case waiting for
a third. The phone layout was this all along — it is now simply the layout.

Pin the alertdialog role so a consumer prop cannot downgrade it, and bring the
docs page back to the compound archetype's section order.

 /**
 * The response row. An alert dialog exists to be answered, so its buttons are anatomy rather
 * than content — the one part `Dialog` deliberately does not ship, because a dialog's footer is
 * whatever the consumer composes and an alert dialog's is always the same two choices.
 *
 * One layout at every width, because that is the convention for a `prompt` generally rather than
 * a rule about alert dialogs: its buttons span the surface, one full width or two at even halves.
 * A right-aligned pair sized to its labels was tried first and is what the designs do not do.
 *
 * A GRID rather than a flex row, and that is what makes both cases the same declaration. Filling
 * the row needs `flex: 1` on each CHILD, which a parent cannot set — StyleX has no child
 * selector, and reaching into the children would mean every call site remembering to pass
 * something. `grid-auto-flow: column` with `grid-auto-columns: 1fr` puts it on the container
 * instead: every button takes an equal share of the row, so one fills it and two split it, with
 * no branch and nothing for a third to break.

fuggin opus.
All these styles are more comments than style. I kinda want to strip them out, but also maybe they're useful context for future agents editing 🤷
any thoughts?

almost wonder if this should just live in Dialog since we'll use in on other prompt sized dialogs for inputs that will have the same styled actions 🤔 . easy swap if so

and move details about role, outside-press dismissal, sizing, and shared
behavior to the relevant later sections.
- Around line 125-132: Reorder the AlertDialog documentation sections to follow
the compound-component sequence: Example, Usage, Parts, then Styling. Change the
“Examples” heading to the existing singular “Example” section and place
“Confirming a discard” beneath it before “Usage,” keeping the Story example
unchanged.

@maxyinger
feat(ui): add Mosaic AlertDialog
d4b461c
A Dialog that interrupts to ask for a decision and waits for one. Base UI's
shape: the same parts as Dialog, with the three props that would let it stop
being an alert dialog removed rather than defaulted — `role` is `alertdialog`,
`closedBy` is `closerequest`, `size` is `prompt`. Everything else is Dialog's
own component rather than a wrapper around it, so there is one implementation
of each and no way for the two to drift.
No `CloseButton` part, for the same reason an outside press cannot dismiss it:
a corner X is a way out without answering.
`AlertDialog.Actions` is the one addition — the response row, which is anatomy
here in a way a dialog's footer is not. A grid rather than a flex row, because
the phone layout is a property on the container instead of something every
button has to be told: `grid-auto-columns` is `1fr` under the sheet band, so
the buttons split the row and span it, and `auto` above it, where the tracks
size to their labels and sit at the inline end. Full-width beats a right-aligned
pair floating against one edge of a screen-wide sheet.
The cancel goes first, which makes it the first tabbable element and therefore
what the alert opens focused on — the least destructive choice, with no
`initialFocus` plumbing, and with the keyboard order agreeing with the screen.
Title and Description are both required, and both warn in development when
missing: an alert dialog's description is announced with its name at the moment
it interrupts, so without one the user is choosing between "Cancel" and "Delete"
with nothing saying what is being deleted. The existing name warning skipped any
role but `dialog`, which would have made it silently inert here, and it now
names the component it is complaining about instead of always saying "Dialog".
@maxyinger
feat(ui): split a prompt's actions evenly at every width
e71dea8
The designs give every `prompt` the same footer, alert dialogs included: one
full-width button, or two at even halves with a 0.75rem gap. Not a pair sized to
their labels against the inline end, which is what this shipped as.
So the media branch goes, and the row gets shorter rather than longer:
`grid-auto-columns: 1fr` unconditionally already means one button fills the row
and two split it, with nothing to switch on at 48rem and no edge case waiting for
a third. The phone layout was this all along — it is now simply the layout.

Pin the alertdialog role so a consumer prop cannot downgrade it, and bring the
docs page back to the compound archetype's section order.

 /**
 * The response row. An alert dialog exists to be answered, so its buttons are anatomy rather
 * than content — the one part `Dialog` deliberately does not ship, because a dialog's footer is
 * whatever the consumer composes and an alert dialog's is always the same two choices.
 *
 * One layout at every width, because that is the convention for a `prompt` generally rather than
 * a rule about alert dialogs: its buttons span the surface, one full width or two at even halves.
 * A right-aligned pair sized to its labels was tried first and is what the designs do not do.
 *
 * A GRID rather than a flex row, and that is what makes both cases the same declaration. Filling
 * the row needs `flex: 1` on each CHILD, which a parent cannot set — StyleX has no child
 * selector, and reaching into the children would mean every call site remembering to pass
 * something. `grid-auto-flow: column` with `grid-auto-columns: 1fr` puts it on the container
 * instead: every button takes an equal share of the row, so one fills it and two split it, with
 * no branch and nothing for a third to break.

fuggin opus.
All these styles are more comments than style. I kinda want to strip them out, but also maybe they're useful context for future agents editing 🤷
any thoughts?

almost wonder if this should just live in Dialog since we'll use in on other prompt sized dialogs for inputs that will have the same styled actions 🤔 . easy swap if so

describing the new Mosaic AlertDialog API.

present-tense paragraph. Retain only its purpose and distinction from Dialog,
and move details about role, outside-press dismissal, sizing, and shared
behavior to the relevant later sections.
- Around line 125-132: Reorder the AlertDialog documentation sections to follow
the compound-component sequence: Example, Usage, Parts, then Styling. Change the
“Examples” heading to the existing singular “Example” section and place
“Confirming a discard” beneath it before “Usage,” keeping the Story example
unchanged.

@maxyinger
feat(ui): add Mosaic AlertDialog
d4b461c
A Dialog that interrupts to ask for a decision and waits for one. Base UI's
shape: the same parts as Dialog, with the three props that would let it stop
being an alert dialog removed rather than defaulted — `role` is `alertdialog`,
`closedBy` is `closerequest`, `size` is `prompt`. Everything else is Dialog's
own component rather than a wrapper around it, so there is one implementation
of each and no way for the two to drift.
No `CloseButton` part, for the same reason an outside press cannot dismiss it:
a corner X is a way out without answering.
`AlertDialog.Actions` is the one addition — the response row, which is anatomy
here in a way a dialog's footer is not. A grid rather than a flex row, because
the phone layout is a property on the container instead of something every
button has to be told: `grid-auto-columns` is `1fr` under the sheet band, so
the buttons split the row and span it, and `auto` above it, where the tracks
size to their labels and sit at the inline end. Full-width beats a right-aligned
pair floating against one edge of a screen-wide sheet.
The cancel goes first, which makes it the first tabbable element and therefore
what the alert opens focused on — the least destructive choice, with no
`initialFocus` plumbing, and with the keyboard order agreeing with the screen.
Title and Description are both required, and both warn in development when
missing: an alert dialog's description is announced with its name at the moment
it interrupts, so without one the user is choosing between "Cancel" and "Delete"
with nothing saying what is being deleted. The existing name warning skipped any
role but `dialog`, which would have made it silently inert here, and it now
names the component it is complaining about instead of always saying "Dialog".
@maxyinger
feat(ui): split a prompt's actions evenly at every width
e71dea8
The designs give every `prompt` the same footer, alert dialogs included: one
full-width button, or two at even halves with a 0.75rem gap. Not a pair sized to
their labels against the inline end, which is what this shipped as.
So the media branch goes, and the row gets shorter rather than longer:
`grid-auto-columns: 1fr` unconditionally already means one button fills the row
and two split it, with nothing to switch on at 48rem and no edge case waiting for
a third. The phone layout was this all along — it is now simply the layout.

Pin the alertdialog role so a consumer prop cannot downgrade it, and bring the
docs page back to the compound archetype's section order.

 /**
 * The response row. An alert dialog exists to be answered, so its buttons are anatomy rather
 * than content — the one part `Dialog` deliberately does not ship, because a dialog's footer is
 * whatever the consumer composes and an alert dialog's is always the same two choices.
 *
 * One layout at every width, because that is the convention for a `prompt` generally rather than
 * a rule about alert dialogs: its buttons span the surface, one full width or two at even halves.
 * A right-aligned pair sized to its labels was tried first and is what the designs do not do.
 *
 * A GRID rather than a flex row, and that is what makes both cases the same declaration. Filling
 * the row needs `flex: 1` on each CHILD, which a parent cannot set — StyleX has no child
 * selector, and reaching into the children would mean every call site remembering to pass
 * something. `grid-auto-flow: column` with `grid-auto-columns: 1fr` puts it on the container
 * instead: every button takes an equal share of the row, so one fills it and two split it, with
 * no branch and nothing for a third to break.

fuggin opus.
All these styles are more comments than style. I kinda want to strip them out, but also maybe they're useful context for future agents editing 🤷
any thoughts?

almost wonder if this should just live in Dialog since we'll use in on other prompt sized dialogs for inputs that will have the same styled actions 🤔 . easy swap if so

Yeah I could see this living in Dialog since it isn't specific to Alert dialog

describing the new Mosaic AlertDialog API.
In `@packages/swingset/src/stories/alert-dialog.component.mdx`:

present-tense paragraph. Retain only its purpose and distinction from Dialog,
and move details about role, outside-press dismissal, sizing, and shared
behavior to the relevant later sections.
- Around line 125-132: Reorder the AlertDialog documentation sections to follow
the compound-component sequence: Example, Usage, Parts, then Styling. Change the
“Examples” heading to the existing singular “Example” section and place
“Confirming a discard” beneath it before “Usage,” keeping the Story example
unchanged.

@maxyinger
feat(ui): add Mosaic AlertDialog
d4b461c
A Dialog that interrupts to ask for a decision and waits for one. Base UI's
shape: the same parts as Dialog, with the three props that would let it stop
being an alert dialog removed rather than defaulted — `role` is `alertdialog`,
`closedBy` is `closerequest`, `size` is `prompt`. Everything else is Dialog's
own component rather than a wrapper around it, so there is one implementation
of each and no way for the two to drift.
No `CloseButton` part, for the same reason an outside press cannot dismiss it:
a corner X is a way out without answering.
`AlertDialog.Actions` is the one addition — the response row, which is anatomy
here in a way a dialog's footer is not. A grid rather than a flex row, because
the phone layout is a property on the container instead of something every
button has to be told: `grid-auto-columns` is `1fr` under the sheet band, so
the buttons split the row and span it, and `auto` above it, where the tracks
size to their labels and sit at the inline end. Full-width beats a right-aligned
pair floating against one edge of a screen-wide sheet.
The cancel goes first, which makes it the first tabbable element and therefore
what the alert opens focused on — the least destructive choice, with no
`initialFocus` plumbing, and with the keyboard order agreeing with the screen.
Title and Description are both required, and both warn in development when
missing: an alert dialog's description is announced with its name at the moment
it interrupts, so without one the user is choosing between "Cancel" and "Delete"
with nothing saying what is being deleted. The existing name warning skipped any
role but `dialog`, which would have made it silently inert here, and it now
names the component it is complaining about instead of always saying "Dialog".
@maxyinger
feat(ui): split a prompt's actions evenly at every width
e71dea8
The designs give every `prompt` the same footer, alert dialogs included: one
full-width button, or two at even halves with a 0.75rem gap. Not a pair sized to
their labels against the inline end, which is what this shipped as.
So the media branch goes, and the row gets shorter rather than longer:
`grid-auto-columns: 1fr` unconditionally already means one button fills the row
and two split it, with nothing to switch on at 48rem and no edge case waiting for
a third. The phone layout was this all along — it is now simply the layout.

Pin the alertdialog role so a consumer prop cannot downgrade it, and bring the
