Paste it into your composition
Opencompositions/components/focus-rack.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
you paste it into.
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_a | Draft | string | Label on the card that begins in focus. |
label_b | Published | string | Label on the card that receives focus. |
accent | blue | green, blue, violet | Highlight color shared by both cards. |
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="focus-rack"
data-composition-src="compositions/components/focus-rack.html"
data-variable-values='{"label_a":"Draft","label_b":"Published","accent":"blue"}'
></div>

<!--
focus-rack: HyperFrames video primitive (camera / holdable / emphasize)
Concept: two cards sit at different apparent depths. Card A begins sharp
and near while card B is blurred and dim. Focus moves to card B exactly
once, with blur, scale, and parallax changing together over 0.7 seconds.
Variables:
- label_a (string, default "Draft"): foreground card label.
- label_b (string, default "Published"): background card label.
- accent (green | blue | violet, default "blue"): focus highlight.
Envelope (fixed IN/OUT, elastic HOLD only, never gsap.timeScale()):
IN_BASE = 1.32s stage reveal, initial focus beat, then one 0.7s rack
HOLD = elastic card B remains sharp with a restrained depth drift
OUT_BASE = 0.42s completed focus state fades from the stage
If D is shorter than IN_BASE plus OUT_BASE, both fixed phases compress
proportionally and HOLD becomes zero. The rack still occurs exactly once.
Mount contract: the runtime clones only this template. #root fills the host
box, establishes the container query basis, has no data-width or data-height,
and registers one paused timeline under the hardcoded focus-rack id.
