Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔵 Low · up to The PR improves Linux WebM buffer ownership and adds export lifecycle coverage. It is mergeable with owner awareness because Escape can still change editor selection while the linked-delete dialog is open and caption loading can ignore reduced-motion preferences; these are bounded UX/accessibility issues rather than release-blocking export risks.

Keep VideoEditor.vue within the source-file limit.
This file has 851 lines. Split a cohesive editor section with the new linked-deletion integration so the resulting source files are at most 500 lines.
As per coding guidelines, “no source file over 500 lines, types in dedicated type files, readable small units, and tests for TypeScript and Rust changes.”
