Summary

This PR brings 5 UI layout improvements and fixes across the editor:

  1. Chat sidebar closed by default & auto-open on AI request: The editor now opens with the AI chat sidebar closed by default (chatOpen: false). Clicking "Coupes intelligentes" (or submitting an AI action to useChatPromptBus) automatically opens the sidebar, and the prompt is immediately consumed and run.
  2. Slider gauge fill color: Sliders now compute --slider-pct and render a linear-gradient track filled with var(--brand) up to the thumb (plus ::-moz-range-progress for Firefox). Replaced the raw webcam size slider in LayoutPane with SliderCell full.
  3. Camera layout button icon: Changed the "Disposition caméra" button icon on the facet rail and inside LayoutPane's header from LayoutIcon to Camera.
  4. Close cross on Audio and facet panels: Replaced the chevron collapse button on facet panels (FacetBody) with an X icon matching the timeline pill inspector headers (SelectionPane).
  5. Subtitles sub-panel design polish:
    • Removed redundant header icon that conflicted with the close button.
    • Removed rigid maxWidth: 160 on select elements; updated with minWidth: 120, padding: 0 10px, and background: var(--surface-2).
    • Adapted translation row with flex: 1, minWidth: 0 to fill available width.
    • Standardized empty state and legacy caption cards on var(--surface-2).
    • Redesigned .paneTabs segmented controls (position anchor) to have elevated active tabs on var(--surface-2) rather than a harsh neon green button.

📝 Walkthrough

Walkthrough

The editor updates pane presentation, captions dismissal, pending chat prompt handling, shared slider rendering, and selected audio-track inspection. Tests cover chat reopening, slider bounds, captions closing, and audio-track close behavior.

Changes

AI editor updates

Layer / File(s) Summary
Pane and caption presentation
src/components/ai-edition/NewEditorShell.module.css, src/components/ai-edition/CaptionsPane.tsx, src/components/ai-edition/RightPanes.tsx, src/components/ai-edition/TranscriptPane.captions.test.tsx
Updates pane tabs, caption layout, caption dismissal, surfaces, and select controls.
Pending chat prompt flow
src/components/ai-edition/NewEditorShell.tsx, src/components/ai-edition/NewEditorShell.chatOpen.test.tsx
Starts the chat panel closed and opens it when a pending prompt exists. Tests cover prompt consumption, manual closing, and reopening.
Shared slider and pane controls
src/components/ai-edition/RightPanes.tsx, src/components/ai-edition/NewEditorShell.module.css, src/components/ai-edition/SliderCell.test.tsx
Adds clamped slider progress, full-width support, pane icons, header actions, and close controls. The PiP webcam-size control uses SliderCell.
Audio-track inspector behavior
src/components/ai-edition/RightPanes.tsx, src/components/ai-edition/v4/FloatingInspector.tsx, src/components/ai-edition/v4/FloatingInspector.test.tsx, src/components/ai-edition/AudioTrackPane.test.tsx
Adds selected audio-track controls, asynchronous update handling, reset behavior, and close handling. Updates the inspector camera icon and close-button styling.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 1980c

This UI update closes chat by default while reopening it for new AI prompts, refines editor controls, and improves audio-track reset behavior. The covered interaction and boundary paths leave no identified merge-blocking risk.

Inline comments:
In `@src/components/ai-edition/CaptionsPane.tsx`:
- Line 578: Update the shared selectStyle used by the five CaptionsPane selects
so keyboard focus remains visibly indicated: remove the outline:none rule or
provide an equivalent :focus-visible replacement for the .paneRow controls,
while preserving other select styling.

In `@src/components/ai-edition/NewEditorShell.tsx`:
- Around line 114-120: The NewEditorShell chat behavior lacks regression
coverage. Add a Vitest test in the same package that verifies the panel
initially starts closed and transitions open when useChatPromptBus provides a
non-empty pending prompt, covering both observable states.
- Around line 115-120: Add same-package regression coverage for the
ChatStripPanel prompt flow: submit a prompt, verify the panel opens, consume it
via send(), close the panel, and confirm a normally delivered prompt reopens it.
Use the existing pendingPrompt and send() behavior rather than changing
unrelated components.

In `@src/components/ai-edition/RightPanes.tsx`:
- Line 2021: Update LayoutPane’s Pane header so the Camera icon is rendered in
the visible pane header rather than only passed through the hidden icon prop;
otherwise remove this no-op icon change. Preserve the existing title and
helpText behavior.

In `@src/components/ai-edition/SliderCell.test.tsx`:
- Around line 23-47: Update the test “clamps --slider-pct to 0% and 100% at
boundaries” to render values outside the configured range, such as below min and
above max, and assert the CSS property remains 0% and 100% respectively. Keep
the existing SliderCell setup and verify both clamping behaviors in the same
test.

1046-1047: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use the close affordance for facet panes.

FacetBody still renders ChevronRight and labels the button as inspector.collapseInspector. The requested facet-pane control is a close (X) button. Render X, use the close label, and update src/components/ai-edition/v4/FloatingInspector.test.tsx to assert that contract.

Suggested change
-			<ChevronRight size={15} />
+			<X size={15} />
