Summary

The camera bubble currently has a fixed shadow. Add independent None, Light, Medium and Strong controls in Camera layout, persist the selection, and carry it through the shared native compositor for preview and export. Existing projects and scene payloads default to the historical appearance; cutout and non-PiP layouts retain their existing behavior.

Related issue

Refs #1490. This covers the shadow portion; camera border width and colour are outside this PR.

Type of change

• Feature

Release impact

• Minor

Desktop impact

• Not platform-specific

Screenshots / video

No screenshot: the available local fixture has no camera track, so visual camera preview and exported frames have not been verified.

Testing

• Node 22: 377 unit test files, 5,253 passed and 2 skipped; both TypeScript checks passed; Biome reports no errors and 36 existing warnings.
• Added coverage for default and invalid values, project persistence, four UI choices and native scene serialization.
• macOS Apple Silicon: compiled the LGPL FFmpeg SDK and native compositor addon; shared Rust geometry shadow scaling and layout-transition tests passed.
• Opened the isolated desktop editor; camera shadow controls and visual preview/export were not manually exercised because the local fixture has no camera track. Physical camera, Windows and Linux were not tested.

Summary by CodeRabbit

• New Features
  • Added an independent webcam picture-in-picture shadow control, with options ranging from no shadow to a stronger shadow. It defaults to Medium and is saved with your project.
  • Shadow controls appear when the webcam background is not transparent.
• Bug Fixes
  • Webcam shadow strength now follows the selected setting without affecting composition shadow or picture-in-picture sizing.

Walkthrough

The editor adds a configurable webcam shadow intensity setting. Scene descriptions carry the setting to the compositor, which scales the webcam shadow weight while leaving the webcam destination unchanged.

Changes: Webcam shadow intensity

Layer / File(s)	Summary
Setting defaults, storage, and editor control src/lib/projectDefaults.ts, src/lib/ai-edition/store/editorSettings.ts, src/lib/ai-edition/store/editorSettings.test.ts, src/components/ai-edition/RightPanes.tsx, src/components/ai-edition/RightPanes.layout.test.tsx	The editor setting defaults to 0.6 and is bounded to 0..1. LayoutPane shows a camera shadow control when the webcam background is not transparent. Tests cover defaulting, persistence, bounds, and control selection.
Scene description setting src/native/sceneDescription.ts, src/native/sceneDescription.test.ts, crates/compositor/src/scene.rs	SceneEffects gains an optional webcam shadow value. buildSceneDescription serializes the editor setting. Tests cover independent values and the default.
Compositor shadow scaling crates/compositor/src/frame_geometry.rs, crates/compositor/src/compositor_windows.rs	plan_frame scales the layout-derived shadow weight using the scene value. The compositor comment now describes the shadow as configurable. Tests cover scaling and confirm that the webcam destination does not change.

Merge Risk: Low · up to edade

Some imported values display no selection, fallback shadows cannot be adjusted, and presets do not preserve the setting. These bounded issues warrant owner awareness and follow-up.

Assert that the composition shadow stays unchanged.

This test checks only webcamShadowIntensity. A handler that also changes shadowIntensity would pass. Seed a composition-shadow value and assert it after each camera-shadow click.

Pin the PiP shadow baseline.

If plan_frame returns zero for every intensity, all scaling assertions pass. Assert the historical baseline to detect that regression.

Suggested fix

- Line 2938: Update the camera shadow row’s disabled condition to depend only on
layoutControlsDisabled, removing the transparent-mode restriction so the
fallback shadow remains adjustable.
- Line 2937: Update the webcamShadowIntensity control so values that do not
match one of its four presets still visibly show the current custom strength.
Keep the stored value unchanged and preserve the existing preset choices and
behavior.

Review comments at @src/lib/projectDefaults.ts:
- Line 300: Update the appearance preset flow for webcamShadowIntensity so
preset capture stores it, parsing accepts it, and application restores it; also
include it when copying appearance settings into a new project. Keep older
presets valid when this field is absent, preserving the existing fallback
behavior.

Thanks a lot for this, @swording-k! It's a clean change. I pushed a small tweak (the control is now hidden rather than disabled in cutout mode) and verified the export with a camera track. Merging once CI is green.
