## Install

<InstallCommand command="npx hyperframes add trust-strip" />

That writes one file: `compositions/components/trust-strip.html`.

## Paste it into your composition

Open `compositions/components/trust-strip.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                                                                                      |
| -------- | ---------------------------------------------- | ------------------------- | ------------------------------------------------------------------------------------------------- |
| `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.                                               |

Set them with `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:

```html wrap theme={null}
<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"}'
></div>
```

    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.
