refactor(theme): reduce theme schema to 20 colors

[StiensWout]

Follow-up to #7107.

The Advanced theme creator exposes 20 controls, but the stored schema and runtime still maintained 57 source colors.

This reduces the shared schema, every built-in palette, imports, exports, and web runtime inputs to the same 20 colors. Web and mobile semantic colors are derived from those sources, known legacy v1 roles remain import-compatible, and the current editor layout is unchanged.

The theme inspector now finds semantic utility usage without changing live theme colors. Its accent highlight is attached to matched elements, so it stays aligned while scrolling and clears immediately on Cancel.

Verification

• 81 focused web theme service tests
• 20 focused mobile theme service tests
• Web, mobile, and shared typechecks
• Targeted lint and formatting
• Production web build
• Browser-verified token selection, scrolling, and Cancel cleanup
• Light and dark captures for every built-in theme at 1440×900, with pairwise SSIM of at least 0.9996

Note

Reduce theme schema from ~57 roles to 20 source roles with derived semantic colors

• Replaces the large --app-theme-* CSS variable set with 20 --theme-* source roles; derived semantic variables (foregrounds, surfaces, status colors) are computed at runtime by the new deriveThemeSemanticColors function in themePalette.ts.
• Built-in theme definitions in themePalettes.ts drop dozens of previously stored roles (toolbar, sidebar, terminal, muted, placeholder, focus, etc.); textMuted is renamed to mutedForeground.
• The theme inspector in themeInspector.ts is rewritten to detect roles from Tailwind utility classes and data attributes instead of computed-style probing; spotlight overlay rendering is removed.
• Mobile theme variables in mobileTheme.ts switch sheets from chrome to canvas and compute foregrounds for readability against their surfaces.
• Boot-time splash color in index.html now uses canvas instead of chrome for document background and meta theme-color.
• Risk: any code or saved theme files referencing removed roles (e.g. sidebarForeground, terminalCursor, accentForeground) will silently receive no value; legacy keys in override files are now skipped rather than applied.

Note

Medium Risk
Wide theme contract change across web, mobile, boot, and imports; visual parity relies on derivation and extensive tests rather than per-role storage.

Overview
Aligns stored themes with the Advanced editor by shrinking the shared palette from ~57 roles to 20 source colors (canvas, text, accent, surfaces, sidebar, terminal, status hues, etc.). Built-in palettes, VS Code import, and exports use only those roles; legacy v1 keys (e.g. chrome, terminalCursor) are still accepted on import but dropped from serialized files.

Runtime semantics are derived, not stored. Web adds deriveThemeSemanticColors and paints --theme-* source variables plus computed pairs (--primary-foreground, error/warning surfaces, terminal text, etc.) via a new CSS bridge. Mobile maps the same roles into native variables with contrast-aware foreground helpers. Terminal theming uses text / accent instead of removed terminal-specific foreground/cursor roles.

Editor and boot paths follow the slimmer model: advanced color families map one role each; boot splash drops chrome and keys document/meta color off canvas. The theme inspector no longer probes live CSS with sentinel colors or a spotlight overlay—it highlights matches from Tailwind utilities, responsive variants, and data-theme-terminal-surface / data-theme-code-surface markers.

Reviewed the theme token reduction for consistency with the runtime token bridge and themed contrast behavior. Four concrete findings, all in the new CSS derivation layer and its consumers:

• index.css derives every surface foreground from --theme-text, dropping the per-surface contrast solving that the removed palette roles provided (the repo's own inverted-surface VS Code import fixture now produces ~1.0:1 sidebar/terminal text).
• Solid action/destructive foregrounds are only contrast-solved inside @supports (color: contrast-color(red)); the fallback path lands well below AA on the shipped built-in palettes.
• themeInspector.ts maps several *-foreground utilities to surface roles that no longer drive them, so the inspector's fast path resolves the wrong editable swatch.
• ThemeImportDialog.tsx swapped runtime --theme-* inputs for always-defined semantic tokens, which kills the intended JSON highlight fallbacks.

Reviewed the theme-token reduction for UI/theming consistency. The 20-role schema and the runtime --theme-* bridge look coherent, and the editor/label/family plumbing matches the new role list. Six concrete regressions in the derived semantic layer are flagged inline: solid-control and status foregrounds are no longer contrast-solved (measured below AA on shipped built-ins), --destructive-foreground loses its red signal, the T3 Chat branded sidebar edge and light-mode toolbar hover direction change, the theme inspector now selects surface roles for text tokens, and the JSON preview highlighter lost its fallbacks.

Reviewed the web-side theme token reduction (apps/web/src/** CSS/TS). The runtime contrast service now fills the foreground/status pairs, which resolves the earlier readability findings on --primary-foreground, --destructive-foreground, and the status families, and the T3 Chat sidebar edge is preserved. Three remaining issues, all in the inspector/runtime plumbing.

One new finding on the themed token bridge: the derived hover fill for the primary action can now drop the label below AA. Earlier findings from previous runs on this PR (--placeholder/--sidebar-muted-foreground solved only against canvas, the inspector's variant handling in the hit test, and the unread data-theme-custom attribute) still apply and are not repeated here.

This refactors the theme contract across 20 files without fixing a current user-facing or reliability problem. The broad migration cost is not justified.

The theme inspector no longer probes live CSS with sentinel colors or a spotlight overlay—it highlights matches from Tailwind utilities, responsive variants, and data-theme-terminal-surface / data-theme-code-surface markers.

Reviewed the theme token reduction for consistency with the runtime token bridge and themed contrast behavior. Four concrete findings, all in the new CSS derivation layer and its consumers:

• index.css derives every surface foreground from --theme-text, dropping the per-surface contrast solving that the removed palette roles provided (the repo's own inverted-surface VS Code import fixture now produces ~1.0:1 sidebar/terminal text).
• Solid action/destructive foregrounds are only contrast-solved inside @supports (color: contrast-color(red)); the fallback path lands well below AA on the shipped built-in palettes.
• themeInspector.ts maps several *-foreground utilities to surface roles that no longer drive them, so the inspector's fast path resolves the wrong editable swatch.
• ThemeImportDialog.tsx swapped runtime --theme-* inputs for always-defined semantic tokens, which kills the intended JSON highlight fallbacks.

We're closing this PR as we clean up the T3 Code backlog. Thank you for taking the time to put this together.

This refactors the theme contract across 20 files without fixing a current user-facing or reliability problem. The broad migration cost is not justified.

Follow-up to #7107.

The Advanced theme creator exposes 20 controls, but the stored schema and runtime still maintained 57 source colors.

This reduces the shared schema, every built-in palette, imports, exports, and web runtime inputs to the same 20 colors. Web and mobile semantic colors are derived from those sources, known legacy v1 roles remain import-compatible, and the current editor layout is unchanged.

The theme inspector now finds semantic utility usage without changing live theme colors. Its accent highlight is attached to matched elements, so it stays aligned while scrolling and clears immediately on Cancel.

Verification

• 81 focused web theme service tests
• 20 focused mobile theme service tests
• Web, mobile, and shared typechecks
• Targeted lint and formatting
• Production web build
• Browser-verified token selection, scrolling, and Cancel cleanup
• Light and dark captures for every built-in theme at 1440×900, with pairwise SSIM of at least 0.9996

Reduce theme schema from ~57 roles to 20 source roles with derived semantic colors

• Replaces the large --app-theme-* CSS variable set with 20 --theme-* source roles; derived semantic variables (foregrounds, surfaces, status colors) are computed at runtime by the new deriveThemeSemanticColors function in themePalette.ts.
• Built-in theme definitions in themePalettes.ts drop dozens of previously stored roles (toolbar, sidebar, terminal, muted, placeholder, focus, etc.); textMuted is renamed to mutedForeground.
• The theme inspector in themeInspector.ts is rewritten to detect roles from Tailwind utility classes and data attributes instead of computed-style probing; spotlight overlay rendering is removed.
• Mobile theme variables in mobileTheme.ts switch sheets from chrome to canvas and compute foregrounds for readability against their surfaces.
• Boot-time splash color in index.html now uses canvas instead of chrome for document background and meta theme-color.
• Risk: any code or saved theme files referencing removed roles (e.g. sidebarForeground, terminalCursor, accentForeground) will silently receive no value; legacy keys in override files are now skipped rather than applied.

Note

Medium Risk
Wide theme contract change across web, mobile, boot, and imports; visual parity relies on derivation and extensive tests rather than per-role storage.

Overview
Aligns stored themes with the Advanced editor by shrinking the shared palette from ~57 roles to 20 source colors (canvas, text, accent, surfaces, sidebar, terminal, status hues, etc.). Built-in palettes, VS Code import, and exports use only those roles; legacy v1 keys (e.g. chrome, terminalCursor) are still accepted on import but dropped from serialized files.

Runtime semantics are derived, not stored. Web adds deriveThemeSemanticColors and paints --theme-* source variables plus computed pairs (--primary-foreground, error/warning surfaces, terminal text, etc.) via a new CSS bridge. Mobile maps the same roles into native variables with contrast-aware foreground helpers. Terminal theming uses text / accent instead of removed terminal-specific foreground/cursor roles.

Editor and boot paths follow the slimmer model: advanced color families map one role each; boot splash drops chrome and keys document/meta color off canvas. The theme inspector no longer probes live CSS with sentinel colors or a spotlight overlay—it highlights matches from Tailwind utilities, responsive variants, and data-theme-terminal-surface / data-theme-code-surface markers.

Approvability

Verdict: Needs human review

Major refactor reducing theme schema from 57 to 20 colors with new runtime derivation logic for semantic colors. Changes fundamental theming architecture including CSS variable mapping, theme inspector, and built-in theme definitions.

Reviewed the web-side theme token reduction (apps/web/src/** CSS/TS). The runtime contrast service now fills the foreground/status pairs, which resolves the earlier readability findings on --primary-foreground, --destructive-foreground, and the status families, and the T3 Chat sidebar edge is preserved. Three remaining issues, all in the inspector/runtime plumbing.

One new finding on the themed token bridge: the derived hover fill for the primary action can now drop the label below AA. Earlier findings from previous runs on this PR (--placeholder/--sidebar-muted-foreground solved only against canvas, the inspector's variant handling in the hit test, and the unread data-theme-custom attribute) still apply and are not repeated here.

One finding on the new variant-activity check in themeInspector.ts. The rest of this round looks good: the semantic foregrounds are now contrast-solved in deriveThemeSemanticColors (including placeholder and sidebarMutedForeground against their own surfaces), the JSON highlighter is back on runtime-only --theme-* inputs so its fallbacks stay reachable, and the toolbar hover is derived from the resting control fill.

We're closing this PR as we clean up the T3 Code backlog. Thank you for taking the time to put this together.

This refactors the theme contract across 20 files without fixing a current user-facing or reliability problem. The broad migration cost is not justified.

If you believe we closed this in error, please reopen the PR and leave a comment explaining what we missed.

Follow-up to #7107.

The Advanced theme creator exposes 20 controls, but the stored schema and runtime still maintained 57 source colors.

This reduces the shared schema, every built-in palette, imports, exports, and web runtime inputs to the same 20 colors. Web and mobile semantic colors are derived from those sources, known legacy v1 roles remain import-compatible, and the current editor layout is unchanged.

The theme inspector now finds semantic utility usage without changing live theme colors. Its accent highlight is attached to matched elements, so it stays aligned while scrolling and clears immediately on Cancel.

Verification

• 81 focused web theme service tests
• 20 focused mobile theme service tests
• Web, mobile, and shared typechecks
• Targeted lint and formatting
• Production web build
• Browser-verified token selection, scrolling, and Cancel cleanup
• Light and dark captures for every built-in theme at 1440×900, with pairwise SSIM of at least 0.9996

Reduce theme schema from ~57 roles to 20 source roles with derived semantic colors

• Replaces the large --app-theme-* CSS variable set with 20 --theme-* source roles; derived semantic variables (foregrounds, surfaces, status colors) are computed at runtime by the new deriveThemeSemanticColors function in themePalette.ts.
• Built-in theme definitions in themePalettes.ts drop dozens of previously stored roles (toolbar, sidebar, terminal, muted, placeholder, focus, etc.); textMuted is renamed to mutedForeground.
• The theme inspector in themeInspector.ts is rewritten to detect roles from Tailwind utility classes and data attributes instead of computed-style probing; spotlight overlay rendering is removed.
• Mobile theme variables in mobileTheme.ts switch sheets from chrome to canvas and compute foregrounds for readability against their surfaces.
• Boot-time splash color in index.html now uses canvas instead of chrome for document background and meta theme-color.
• Risk: any code or saved theme files referencing removed roles (e.g. sidebarForeground, terminalCursor, accentForeground) will silently receive no value; legacy keys in override files are now skipped rather than applied.

Note

Medium Risk
Wide theme contract change across web, mobile, boot, and imports; visual parity relies on derivation and extensive tests rather than per-role storage.

Overview
Aligns stored themes with the Advanced editor by shrinking the shared palette from ~57 roles to 20 source colors (canvas, text, accent, surfaces, sidebar, terminal, status hues, etc.). Built-in palettes, VS Code import, and exports use only those roles; legacy v1 keys (e.g. chrome, terminalCursor) are still accepted on import but dropped from serialized files.

Runtime semantics are derived, not stored. Web adds deriveThemeSemanticColors and paints --theme-* source variables plus computed pairs (--primary-foreground, error/warning surfaces, terminal text, etc.) via a new CSS bridge. Mobile maps the same roles into native variables with contrast-aware foreground helpers. Terminal theming uses text / accent instead of removed terminal-specific foreground/cursor roles.

Editor and boot paths follow the slimmer model: advanced color families map one role each; boot splash drops chrome and keys document/meta color off canvas. The theme inspector no longer probes live CSS with sentinel colors or a spotlight overlay—it highlights matches from Tailwind utilities, responsive variants, and data-theme-terminal-surface / data-theme-code-surface markers.

Reviewed the theme token reduction for consistency with the runtime token bridge and themed contrast behavior. Four concrete findings, all in the new CSS derivation layer and its consumers:

• index.css derives every surface foreground from --theme-text, dropping the per-surface contrast solving that the removed palette roles provided (the repo's own inverted-surface VS Code import fixture now produces ~1.0:1 sidebar/terminal text).
• Solid action/destructive foregrounds are only contrast-solved inside @supports (color: contrast-color(red)); the fallback path lands well below AA on the shipped built-in palettes.
• themeInspector.ts maps several *-foreground utilities to surface roles that no longer drive them, so the inspector's fast path resolves the wrong editable swatch.
• ThemeImportDialog.tsx swapped runtime --theme-* inputs for always-defined semantic tokens, which kills the intended JSON highlight fallbacks.

Reviewed the theme-token reduction for UI consistency and runtime-token behavior. Two concrete regressions in changed lines (readable foreground on the themed --primary fill, and the JSON highlight tokens in the import dialog), plus one coverage note on the inspector mapping.

[macroscopeapp]

Reviewed the theme-token reduction for UI/theming consistency. The 20-role schema and the runtime --theme-* bridge look coherent, and the editor/label/family plumbing matches the new role list. Six concrete regressions in the derived semantic layer are flagged inline: solid-control and status foregrounds are no longer contrast-solved (measured below AA on shipped built-ins), --destructive-foreground loses its red signal, the T3 Chat branded sidebar edge and light-mode toolbar hover direction change, the theme inspector now selects surface roles for text tokens, and the JSON preview highlighter lost its fallbacks.
