fix(web-shared): type Tailwind trace viewer duration utility

[tomdale]

Summary

@workflow/web-shared ships the trace viewer controls that downstream apps may include in their Tailwind content scan. The zoom controls used duration-[120ms], which Tailwind v3 can treat as an ambiguous arbitrary utility when scanning the package.

This PR changes those controls to duration-[time:120ms], preserving the same transition duration while giving Tailwind an explicit type hint. It also adds a patch changeset for @workflow/web-shared.

Verification

• rg -n "duration-\[(?!time:)|ease-\[(?!easing-function:)" --pcre2 packages/web-shared/src
• git diff --check
• pnpm --filter @workflow/web-shared lint (blocked by existing unrelated Biome diagnostics in web-shared)
• pnpm --filter @workflow/web-shared typecheck (blocked by existing unrelated attribute-panel.tsx type error)

No backport to stable for 23943f1 (AI decision).

The fix targets packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the new-trace-viewer directory does not exist on stable (only the older trace-viewer/ directory does). A search of web-shared on stable finds no ambiguous duration-[...] Tailwind utilities, so there is no equivalent issue to fix there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

[tomdale]

Summary

@workflow/web-shared ships the trace viewer controls that downstream apps may include in their Tailwind content scan. The zoom controls used duration-[120ms], which Tailwind v3 can treat as an ambiguous arbitrary utility when scanning the package.

This PR changes those controls to duration-[time:120ms], preserving the same transition duration while giving Tailwind an explicit type hint. It also adds a patch changeset for @workflow/web-shared.

Verification

• rg -n "duration-\[(?!time:)|ease-\[(?!easing-function:)" --pcre2 packages/web-shared/src
• git diff --check
• pnpm --filter @workflow/web-shared lint (blocked by existing unrelated Biome diagnostics in web-shared)
• pnpm --filter @workflow/web-shared typecheck (blocked by existing unrelated attribute-panel.tsx type error)

No backport to stable for 23943f1 (AI decision).

The fix targets packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the new-trace-viewer directory does not exist on stable (only the older trace-viewer/ directory does). A search of web-shared on stable finds no ambiguous duration-[...] Tailwind utilities, so there is no equivalent issue to fix there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

[tomdale]

Summary

@workflow/web-shared ships the trace viewer controls that downstream apps may include in their Tailwind content scan. The zoom controls used duration-[120ms], which Tailwind v3 can treat as an ambiguous arbitrary utility when scanning the package.

This PR changes those controls to duration-[time:120ms], preserving the same transition duration while giving Tailwind an explicit type hint. It also adds a patch changeset for @workflow/web-shared.

Verification

• rg -n "duration-\[(?!time:)|ease-\[(?!easing-function:)" --pcre2 packages/web-shared/src
• git diff --check
• pnpm --filter @workflow/web-shared lint (blocked by existing unrelated Biome diagnostics in web-shared)
• pnpm --filter @workflow/web-shared typecheck (blocked by existing unrelated attribute-panel.tsx type error)

No backport to stable for 23943f1 (AI decision).

The fix targets packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the new-trace-viewer directory does not exist on stable (only the older trace-viewer/ directory does). A search of web-shared on stable finds no ambiguous duration-[...] Tailwind utilities, so there is no equivalent issue to fix there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

[tomdale]

Summary

@workflow/web-shared ships the trace viewer controls that downstream apps may include in their Tailwind content scan. The zoom controls used duration-[120ms], which Tailwind v3 can treat as an ambiguous arbitrary utility when scanning the package.

This PR changes those controls to duration-[time:120ms], preserving the same transition duration while giving Tailwind an explicit type hint. It also adds a patch changeset for @workflow/web-shared.

Verification

• rg -n "duration-\[(?!time:)|ease-\[(?!easing-function:)" --pcre2 packages/web-shared/src
• git diff --check
• pnpm --filter @workflow/web-shared lint (blocked by existing unrelated Biome diagnostics in web-shared)
• pnpm --filter @workflow/web-shared typecheck (blocked by existing unrelated attribute-panel.tsx type error)

No backport to stable for 23943f1 (AI decision).

The fix targets packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the new-trace-viewer directory does not exist on stable (only the older trace-viewer/ directory does). A search of web-shared on stable finds no ambiguous duration-[...] Tailwind utilities, so there is no equivalent issue to fix there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

[tomdale]

Summary

@workflow/web-shared ships the trace viewer controls that downstream apps may include in their Tailwind content scan. The zoom controls used duration-[120ms], which Tailwind v3 can treat as an ambiguous arbitrary utility when scanning the package.

This PR changes those controls to duration-[time:120ms], preserving the same transition duration while giving Tailwind an explicit type hint. It also adds a patch changeset for @workflow/web-shared.

Verification

• rg -n "duration-\[(?!time:)|ease-\[(?!easing-function:)" --pcre2 packages/web-shared/src
• git diff --check
• pnpm --filter @workflow/web-shared lint (blocked by existing unrelated Biome diagnostics in web-shared)
• pnpm --filter @workflow/web-shared typecheck (blocked by existing unrelated attribute-panel.tsx type error)

No backport to stable for 23943f1 (AI decision).

The fix targets packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the new-trace-viewer directory does not exist on stable (only the older trace-viewer/ directory does). A search of web-shared on stable finds no ambiguous duration-[...] Tailwind utilities, so there is no equivalent issue to fix there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

[tomdale]

Summary

@workflow/web-shared ships the trace viewer controls that downstream apps may include in their Tailwind content scan. The zoom controls used duration-[120ms], which Tailwind v3 can treat as an ambiguous arbitrary utility when scanning the package.

This PR changes those controls to duration-[time:120ms], preserving the same transition duration while giving Tailwind an explicit type hint. It also adds a patch changeset for @workflow/web-shared.

Verification

• rg -n "duration-\[(?!time:)|ease-\[(?!easing-function:)" --pcre2 packages/web-shared/src
• git diff --check
• pnpm --filter @workflow/web-shared lint (blocked by existing unrelated Biome diagnostics in web-shared)
• pnpm --filter @workflow/web-shared typecheck (blocked by existing unrelated attribute-panel.tsx type error)

No backport to stable for 23943f1 (AI decision).

The fix targets packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the new-trace-viewer directory does not exist on stable (only the older trace-viewer/ directory does). A search of web-shared on stable finds no ambiguous duration-[...] Tailwind utilities, so there is no equivalent issue to fix there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

[tomdale]

Summary

@workflow/web-shared ships the trace viewer controls that downstream apps may include in their Tailwind content scan. The zoom controls used duration-[120ms], which Tailwind v3 can treat as an ambiguous arbitrary utility when scanning the package.

This PR changes those controls to duration-[time:120ms], preserving the same transition duration while giving Tailwind an explicit type hint. It also adds a patch changeset for @workflow/web-shared.

Verification

• rg -n "duration-\[(?!time:)|ease-\[(?!easing-function:)" --pcre2 packages/web-shared/src
• git diff --check
• pnpm --filter @workflow/web-shared lint (blocked by existing unrelated Biome diagnostics in web-shared)
• pnpm --filter @workflow/web-shared typecheck (blocked by existing unrelated attribute-panel.tsx type error)

No backport to stable for 23943f1 (AI decision).

The fix targets packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the new-trace-viewer directory does not exist on stable (only the older trace-viewer/ directory does). A search of web-shared on stable finds no ambiguous duration-[...] Tailwind utilities, so there is no equivalent issue to fix there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

[tomdale]

Summary

@workflow/web-shared ships the trace viewer controls that downstream apps may include in their Tailwind content scan. The zoom controls used duration-[120ms], which Tailwind v3 can treat as an ambiguous arbitrary utility when scanning the package.

This PR changes those controls to duration-[time:120ms], preserving the same transition duration while giving Tailwind an explicit type hint. It also adds a patch changeset for @workflow/web-shared.

Verification

• rg -n "duration-\[(?!time:)|ease-\[(?!easing-function:)" --pcre2 packages/web-shared/src
• git diff --check
• pnpm --filter @workflow/web-shared lint (blocked by existing unrelated Biome diagnostics in web-shared)
• pnpm --filter @workflow/web-shared typecheck (blocked by existing unrelated attribute-panel.tsx type error)

No backport to stable for 23943f1 (AI decision).

The fix targets packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the new-trace-viewer directory does not exist on stable (only the older trace-viewer/ directory does). A search of web-shared on stable finds no ambiguous duration-[...] Tailwind utilities, so there is no equivalent issue to fix there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.
