Walkthrough

The PR updates debug UI accessibility and interaction behavior. It adds synchronized theme controls, EXPLAIN loading and error states, keyboard user switching, accessible rendered markup, timeline layout changes, shared focus and typography tokens, responsive styling, and reduced-motion support.

Changes

Theme toggle synchronization

Layer / File(s) Summary
Theme state and accessible labeling
resources/src/core/theme.js, resources/src/core/debug.js, resources/views/_shell.php, resources/tests/theme.test.js
Theme controls now use dynamic action labels, aria-pressed, synchronized icons, and centralized state updates. Tests cover dark, light, and unset themes.

EXPLAIN loading and aggregate controls

Layer / File(s) Summary
EXPLAIN request and control flow
src/Panel/Db/DbQueryRenderer.php, resources/src/panels/db.js, resources/src/styles/main.css, resources/tests/db.test.js, tests/Panel/Db/DbQueryRendererTest.php
EXPLAIN controls now expose linked output containers, coordinate all-row loading and collapse behavior, report errors, and update accessibility state. Tests cover success, failure, busy state, and aggregate toggling.

Keyboard-enabled user switching

Layer / File(s) Summary
Delegated row activation
resources/src/panels/userswitch.js, resources/tests/userswitch-row.test.js
User-switching rows now support mouse, Enter, and Space activation while ignoring interactive child elements and unrelated keys.

Accessible rendered panel output

Layer / File(s) Summary
Status, duration, and filter labels
src/Panel/Router/RouterSectionRenderer.php, src/Panel/Timeline/TimelineRenderer.php, src/View/Grid/ActiveFilterBanner.php, tests/Panel/Router/RouterSectionRendererTest.php, tests/Panel/Timeline/TimelineRendererTest.php, tests/View/Grid/ActiveFilterBannerTest.php
Route logs now show match status badges. Timeline durations appear beside span names. Filter removal and clear-all links now have descriptive ARIA labels.

Shared visual and motion styling

Layer / File(s) Summary
Focus, typography, layout, and motion rules
resources/src/styles/tokens.css, resources/src/styles/fonts.css, resources/src/styles/main.css, resources/src/styles/timeline.css, resources/src/toolbar/toolbar-shadow.css, CHANGELOG.md
Styles add themed focus rings, IBM Plex Sans bold text, request and timeline layouts, responsive wrapping, typography tokens, EXPLAIN error presentation, and reduced-motion rules. The changelog records the UI updates.

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

Merge Risk: 🔵 Low · up to a8c48

The change is mergeable with owner follow-up: one keyboard-activation test can fail when run independently because it relies on state from an earlier test, so test isolation should be fixed. The theme coverage request is a bounded follow-up and does not indicate a known user-facing regression.

Poem

I’m a rabbit with focus rings bright,
Toggling themes from dark into light.
EXPLAIN rows load, then gently fold,
Keyboard hops switch users bold.
Timelines show their times in view—
And reduced motion helps me too.
