HTML5 drag-and-drop doesn't work inside React Flow nodes because
React Flow captures pointer events at a higher level. Switch to
pointer-event-based reorder with visual feedback (dragged item dims,
hover target highlights with blue ring).

Add nodrag class to thumbnail items so React Flow doesn't capture
drag events, allowing the HTML drag-and-drop reorder to work.

All Easing Functions presets were not updating the editor because
handleSelectEasing fell back to the same DEFAULT_CUSTOM_BEZIER for every
non-preset easing. Added EASING_BEZIER_MAP with correct cubic-bezier
values from easings.net and a getEasingBezier() lookup. Also corrected
three PRESET_BEZIERS entries (easeInOutExpo, easeInOutCubic, easeInOutSine)
that diverged from the easings.net source.

After all video frames are processed (phase 1), the final video duration
is known from highestWrittenTimestamp. Audio is now trimmed to that
exact duration before being encoded into the MP4 (phase 2). Prevents
audio tracks from extending beyond the video.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
When videoDuration is 0 (unknown at call time), prepareAudioAsync was
computing targetDuration as max(0.1, 0) = 0.1 seconds, truncating the
audio to 100ms. Now computes the actual decoded audio duration from
buffers and uses that when videoDuration <= 0.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Use MediaBunny as the primary decoder following the documented pattern:
getPrimaryAudioTrack() + canDecode() check + AudioBufferSink.buffers().
Falls back to Web Audio API's decodeAudioData if MediaBunny cannot parse
the format (e.g. unusual codecs). This ensures MediaBunny handles
container formats it supports while Web Audio API catches the rest.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
MediaBunny's Input/BlobSource is designed for video containers and cannot
parse standalone audio files (MP3, WAV, etc.), causing "unsupported format"
errors at getAudioTracks(). Replace with Web Audio API's decodeAudioData
which natively handles all browser-supported audio formats.

Note: nodeDefaults.ts already had videoStitch dimensions and
createDefaultNodeData from Plan 02, so no changes needed there.
