Paste it into your composition
Opencompositions/components/locked-nucleus-orbit.html and copy what is inside into your own composition.
A component has no size or duration of its own. It takes both from the composition

Variables
Every one of these has a default, so the piece works untouched. Set the ones you want to change on the element:| Variable | Default | Accepts | What it does |
|---|---|---|---|
label | core | string | Text displayed inside the fixed center nucleus. |
accent | green | green, blue, violet | Color used by the nucleus, rings, and satellite markers. |
satellites | 4 | 3 to 6, step 1 | Number of orbiting copy chips. |
data-variable-values on the element that mounts it. These are the
defaults, so this behaves exactly like the preview above until you change one:
<div
data-composition-id="locked-nucleus-orbit"
data-composition-src="compositions/components/locked-nucleus-orbit.html"
data-variable-values='{"label":"core","accent":"green","satellites":4}'
></div>

<!--
locked-nucleus-orbit: HyperFrames video primitive (intros / reveals / orbit)
One nucleus stays dead center for the full composition. Satellite rings and
copy chips fade in while orbiting on deterministic index-based phases, then
decelerate into a composed lockup. The nucleus is never a GSAP target.
Variables:
- label (string, default "core"): text inside the fixed nucleus.
- accent (green | blue | violet, default green): active color.
- satellites (number, 3 to 6, default 4): visible satellite count.
Envelope (fixed IN and ORBIT, elastic HOLD, no OUT):
IN_BASE = 0.45s, rings and chips fade in along their orbital arcs
ORBIT_BASE = 1.75s, satellites decelerate into their final phases
HOLD = max(0, D - (IN + ORBIT)), only ring opacity breathes
OUT = 0s, the composed lockup is the final state
If D is shorter than IN_BASE + ORBIT_BASE, IN and ORBIT compress together.
Mount contract: the runtime clones only this template. #root fills the host
box, has no data-width or data-height, and registers one paused timeline
under the hardcoded locked-nucleus-orbit id.
