Restores the 208 catalog items reverted after their previews 404'd in production, this time on the payload mechanism rather than the .html files that caused the outage. The generator no longer writes a preview document to docs/public. That writer, and the machinery under it, existed only to produce files the docs host discards, so it is gone rather than bypassed. Items now embed the composition itself via a payload, which is what the previous change already does for the items that were already in the catalog. The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame. Items that declare variables get the live player plus the static variables table, and reconnecting the explorer to payloads is a follow-up.

## Install
|
|
|
|
<InstallCommand command="npx hyperframes add grain-field" />
|
|
|
|
That writes one file: `compositions/components/grain-field.html`.
|
|
|
|
## Paste it into your composition
|
|
|
|
Open `compositions/components/grain-field.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 |
|
|
| --- | --- | --- | --- |
|
|
| `density` | `fine` | `fine`, `coarse` | Dot size and spacing across the grain field. |
|
|
| `accent` | `green` | `green`, `blue`, `violet` | Accent token family used to color the dots and luminance wash. |
|
|
|
|
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
|
|
<div
|
|
data-composition-id="grain-field"
|
|
data-composition-src="compositions/components/grain-field.html"
|
|
data-variable-values='{"density":"fine","accent":"green"}'
|
|
></div>
|
|
```

<!--
|
|
grain-field: HyperFrames video primitive (backgrounds / ambient)
|
|
|
|
Concept: a fixed repeated dot field drifts slowly across a deep,
|
|
accent-tinted luminance wash. The dots stay intentionally legible at
|
|
gallery-card size so the texture reads as a designed surface.
|
|
|
|
Variables:
|
|
- density (fine | coarse, default fine): controls dot size and spacing.
|
|
- accent (green | blue | violet, default green): colors the dots and wash.
|
|
|
|
Envelope: IN = 0, HOLD = the full elastic duration, OUT = 0. A longer mount
|
|
stretches only the ambient drift cycle.
|
|
|
|
Loop invariant: the phase completes one full sine cycle during HOLD. The
|
|
endpoint is normalized to phase zero before rendering, so t=0 and
|
|
t=duration have exactly the same transform.
|
|
|
|
Sound: none.
|
|
|
|
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 grain-field id.
