Ignition ring
A faint ring ignites with a flash and keeps flowing with light streaks; the centre line rises once it is lit.

Parameters
| Parameter | Type | What it does |
|---|---|---|
| text / radius / tilt | string / px / ratio | ring: the line in its centre after it lights; its half width (560) and tilt (0.34) |
| items / result | string[] / string | converge: 3-6 parts that come together and what they become |
| nodes | [{label, icon?}] | flow: 3-5 nodes in order; icon "page", "chat", "play", "check", "bolt", "gear", "box", "dot" |
| step_ms | ms | flow: node to node; converge: the hold before the pull |
| ease | {"<move>": ease} | retune any named move (see the entry's moves): a preset name ("out-expo"), a cubic-bezier [x1, y1, x2, y2], {spring: [hz, damping]} or {trapezoid: [accel, decel]}. A wrong move name or curve throws, it never falls back. A move measured from a reference clip (the replica workbench's measure/*.json, frame-keyed) becomes a curve without conversion: MV.fitEase(doc, "x", {from: 133, to: 142}) or `motion-fit <file> --measure x --from 133 --to 142 --ease` |
| camera | {focal?, x?, y?, z?} | the scene's camera: pan x / y and push z as numbers or keyframes [[ms, value, ease?], ...]; objects at different depths move differently (real parallax). focal default 1800 |
| brand | hexDefault: #6B5BFF | the site's brand colour; the component derives its accent (>= 3:1 on the stage), surfaces and ink from it |
| stage | "dark" | "light"Default: "dark" | the stage the component sits on |
| display | font stemDefault: "Inter-Bold" | headline stem; name it in the call so the runtime loads it |
| body | font stemDefault: "Inter-Regular" | UI / body stem; name it in the call so the runtime loads it |
| start_ms | msDefault: 300 | when the component starts, ms into the shot |
| background | booleanDefault: false | draw the stage background (off: transparent over the shot's own stage) |
| place | {x, y, w, h, z?} | the component's place in the shot's layout: it fits its 1920x1080 composition into this stage rect (centred, aspect kept); z orders components front to back. Default: the whole stage |
Moves and their curves
Every move is eased on its own. Retune one with ease: { "<move>": <curve> }, a curve name or cubic-bezier handles.
| Move | Curve | What it does |
|---|---|---|
| ignite | out-expo | the ring heating from outline to full light |
| text.in | house | the centre line rising in once the ring is lit |

MV.bind("s3", MV.energy(el, {"variant":"ring","text":"LaunchReel","brand":"#F2A03D","stage":"dark","display":"Inter-Bold","body":"Inter-Regular"}));When to use it in a launch film
An opening that needs energy before any word, or a logo or name revealed inside light at the end.
Why it works
Light that keeps moving holds the eye while nothing else happens; the ignition is the hook's single event.
Do not combine with
- a second glowing element in the same shot
- a light stage with a pale brand colour (the glow washes out)
