Late red wash with heavy vignette

After the last light leak the picture turns hot red and the vignette closes in; mean brightness falls from 95 to about 53 of 255 within 0.8 s and stays there. Escalating tension in the final third of a motivation or finance clip.

Apply this to my video: "Late red wash with heavy vignette" from the 24fps video editor library.
Preset JSON: https://24fps.dev/video-editor/effects/late-red-wash-heavy-vignette-e1x/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).
Field reference: https://24fps.dev/video-editor/llms.txt. Keep sizes as fractions of the frame height so it works at any resolution. Credit: 24fps.dev/video-editor

Technique
Finance clip: red cast and dark corners from 5.9 s to the end, after the 5.3 s orange leak. Source preview audio is voice only (no music bed, no whoosh or hit visible in the spectrogram), so no sound cue is listed.
