In `@src/components/launch/HudWindow.tsx`:
- Line 8: Preserve the default “toaster group” classes when rendering Toaster in
HudWindow, either by including them alongside pointer-events-auto or by updating
Toaster’s class merging so caller classes do not replace its defaults. Keep the
existing toast styling behavior intact.
In `@src/components/video-editor/export/useExportRunner.ts`:
- Line 114: Update the export flow around handleCancelExport and the GIF/MP4
dynamic imports to track cancellation independently of exporterRef. Preserve
cancellation requested while a chunk is loading, cancel the exporter immediately
after assignment when needed, and skip export() if cancellation already
occurred.
In `@src/components/video-editor/SettingsPanel.tsx`:
- Line 1171: Update the guard in the SettingsPanel effect so wallpaper loading
is not skipped when activeEffectSection is "frame" or "crop"; allow those
sections to continue into the loading logic because they render
sceneSectionContent and backgroundSettingsContent, while preserving the existing
early return for unrelated sections.

Inline comments:
In `@src/components/video-editor/export/useExportRunner.ts`:
- Line 150: Update the export flow around each save await, including
saveExportBlob and finalizeExportedVideo, to call exportWasCancelled()
immediately afterward; when cancellation is detected, discard the temporary
output and return before updating pending-save state, showing toasts, or
recording the saved file.
- Around line 499-504: Update the cancellation cleanup in the export runner’s
finally path to restore the captured video playback state when an export paused
a playing video. Apply this only for explicit cancellation, and guard it so a
superseded run cannot alter the newer export session; preserve the existing
cleanup for non-cancelled runs.
In `@src/components/video-editor/SettingsPanel.tsx`:
- Around line 1171-1179: Update the guard in the wallpaper-loading effect to
allow activeEffectSection values beginning with “ext:” alongside “scene”,
“frame”, and “crop”. Preserve the existing early return for unrelated sections
so getAvailableWallpapers() runs whenever the rendered backgroundSettingsContent
is available.
