Dark open, title slam

Open my video with this hook: "Dark open, title slam" from the 24fps video editor library.
Preset JSON: https://24fps.dev/video-editor/hooks/dark-open-title-slam-hook-e2x/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, fg }: main is a wrapper holding my video, filling the root. Then const fx = mount(root, { kind: "text", preset, media }) and call fx.render(seconds) every frame. The preset runs 3.5s from t = 0; offset t to place it later. 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). Check it on my footage: if text is hidden behind the subject or doesn't read against my colours, nudge the layer positions or colours.
This look needs a cut-out of the person: fg is a second copy of my video with the background removed (video with alpha, e.g. WebM VP9 or HEVC with alpha; e.g. npx hyperframes remove-background clip.mp4 -o clip.fg.webm, or any person-segmentation tool such as rembg or MediaPipe), stacked above the other clips.
Replace the demo text with mine: set preset.layers[n].text (use \n for line breaks); if none given, write lines that fit my footage and tell me.
Hook formula: Starts black with [2 caption words] at 0.3 s, snap-up at 0.5 s with a [two-word headline] slam, then accent-colour words on each phrase
Pair with captions preset italic-neon-emphasis-white-base (https://24fps.dev/video-editor/captions/italic-neon-emphasis-white-base/preset.json); the captions kind takes script as [{ w, s, e, emph }], plus karaoke and activeColor.
