Recurring warm light leaks

Apply this to my video: "Recurring warm light leaks" from the 24fps video editor library.
Preset JSON: https://24fps.dev/video-editor/effects/warm-light-leak-drift-recurring-e5x/preset.json (pass its "preset" to the engine).
Engine (MIT, no dependencies, ES module): https://24fps.dev/editor/engine.js. Download the engine next to your page (curl -O) rather than importing cross-origin, then import { mount } from "./engine.js" in a <script type="module"> served over http.
Wiring: root = a position:relative box at the video's size. media = { main }: main is a wrapper holding my video, filling the root. Then const fx = mount(root, { kind: "effect", preset, media }) and call fx.render(seconds) every frame. It is seek-safe: drive it from the GSAP timeline in HyperFrames or call render(frame / fps) in Remotion. Before capturing frames, await (fx.ready ?? document.fonts.ready).
Sound design: swish at 3.36s on leak onset at ~3.1-3.4 s in cinematic wellness_creators (soft hi-band swish +26 dB, low confidence); swish at 4.56s on second leak at ~4.4 s (soft hi-band swish +29 dB, low confidence). In HyperFrames, fetch each with media-use (e.g. npx hyperframes media-use resolve --type sfx --intent "swish" --project .; media-use needs `heygen auth login`, without it use `--local-only`, check with `--doctor`); elsewhere use royalty-free SFX or ones I give you.
