# Trust Strip

A monochrome trust row of wide-tracked mono wordmarks that fade in with an opacity-only left-to-right stagger, then hold dead still.

**Trust Strip**

```html trust-strip.html theme={null}
<!doctype html>
<!--
  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.

Copy npx hyperframes add trust-strip to the clipboard

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>
```

Tagged `motion-primitive` `proof` `trust` `logo-strip` `wordmarks`.
