## Summary - Run `oxfmt .` across the entire codebase to establish formatted baseline - 299 files changed — mechanical formatting only, no logic changes - Double quotes, semicolons, 2-space indent, trailing commas, 100 print width Part 3/4 of [VA-851](https://linear.app/heygen/issue/VA-851/pre-migration-configure-eslint-prettier-and-conventional-commits) ## Test plan - [x] `pnpm format:check` — all 426 files pass - [x] `pnpm -r typecheck` — all packages pass - [x] `pnpm build` — all packages build - [x] All 348 tests pass

VIDEO CLIPS

|
|
|
|
REQUIRED attributes:
|
|
data-start — when the clip appears (seconds)
|
|
data-duration — how long the clip stays on screen (seconds)
|
|
(optional for video/audio — defaults to source duration)
|
|
data-track-index — z-stacking order + timeline track grouping
|
|
(higher = in front, clips on same track cannot overlap)
|
|
|
|
REQUIRED on <video>:
|
|
muted — framework manages audio via separate <audio> element
|
|
playsinline — prevents fullscreen on mobile
|
|
|
|
REQUIRED:
|
|
class="clip" — sets visibility: hidden so framework can manage lifecycle
|
|
|
|
DO NOT:
|
|
- Call video.play(), video.pause(), or set video.currentTime in scripts
|
|
- Toggle visibility in scripts
|
|
- Use the video element for audio (use a separate <audio> element)

AUDIO
|

════════════════════════════════════════════════════
|
|
|
|
Audio is invisible — no class="clip" needed (no visual to hide).
|
|
Use a separate <audio> element even if the source is the same .mp4 file.

The framework syncs audio playback to the timeline position.

Any div with data-start becomes a timed clip.

Content inside can be freely styled with CSS.

Animate visual properties (opacity, transform) with GSAP — fine.

Do NOT animate visibility — the framework owns that.
