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 |
|---|---|---|---|
marks | Northwind, Acme Corp, Globex, Initech, Umbra | string | Comma-separated wordmark texts (3 to 7 recommended). |
tone | muted | muted, ink | Mark color: quiet muted or full-contrast ink. |
cues | “ | string | Comma-separated reveal starts in seconds from mount start. Empty uses the authored 0.15s stagger. |
accent | green | green, blue, violet | Faint palette tint mixed into the mark color. |
exit | none | none, fade, up | End-of-clip behavior. None holds to the last frame. |
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="trust-strip"
data-composition-src="compositions/components/trust-strip.html"
data-variable-values='{"marks":"Northwind, Acme Corp, Globex, Initech, Umbra","tone":"muted","cues":"","accent":"green","exit":"none"}'

<!--
trust-strip: HyperFrames video primitive (proof & stats / trust)
A monochrome trust row: N text wordmarks set in wide-tracked uppercase mono,
a single centered row with wide gaps, no boxes, no borders. Marks fade in
with an opacity-only stagger from left to right, then the strip holds dead
still. Above five marks the row wraps gracefully to a second centered row
when width demands (reading order is preserved).
Variables:
- marks (string, comma list): the wordmark texts, 3 to 7 recommended.
- tone (muted | ink, default "muted"): mark color, var(--muted) or var(--fg).
- cues (string, comma seconds): per-mark reveal starts relative to mount
start. Empty = authored rhythm (first mark at 0.2s, 0.15s gap).
- accent (green | blue | violet, default "green"): a faint 10% tint mixed
into the mark color so the strip sits in the scene palette; the strip
still reads monochrome.
- exit (none | fade | up, default "none"): none holds to the last frame
(frame roots own transitions); fade dissolves; up dissolves with a rise.
Envelope, fixed IN and OUT with elastic HOLD only (never timeScale):
IN = last reveal start + 0.5s fade
HOLD = max(0, D - IN - OUT), dead still
OUT = 0 when exit is none, else 0.45s
If D is shorter than IN + OUT, both compress together (cues included).
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 literal
trust-strip key.
