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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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 text-shimmer" />
|
|
|
|
That writes one file: `compositions/components/text-shimmer.html`.
|
|
|
|
## Paste it into your composition
|
|
|
|
Open `compositions/components/text-shimmer.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 |
|
|
| --- | --- | --- | --- |
|
|
| `text` | `Effortless` | string | Text receiving the single shimmer pass. |
|
|
| `accent` | `green` | `green`, `blue`, `violet` | Hue of the specular shimmer band. |
|
|
| `sweep_at` | `1.2` | 0.2s to 2s, step 0.1s | Requested start time for the shimmer sweep. |
|
|
|
|
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="text-shimmer"
|
|
data-composition-src="compositions/components/text-shimmer.html"
|
|
data-variable-values='{"text":"Effortless","accent":"green","sweep_at":1.2}'
|
|
></div>
|
|
```
|
|
|
|

<!--

|
text-shimmer: HyperFrames video primitive (text effects / drift / emphasize)
|
|
|
|
Concept: a headline remains fixed while one narrow specular band crosses
|
|
its glyphs. The text is clean before and after the pass. There is no
|
|
entrance, exit, pulse, scale, or supporting decoration.
|
|
|
|
Evidence: design-inspiration/INDEX.md and viral-micro-interactions.md,
|
|
animated text shimmer by jhey Tan, adapted from an infinite CSS loop into
|
|
one deterministic, seek-driven video beat.
|
|
|
|
Variables:
|
|
- text (string, default "Effortless"): headline copy.
|
|
- accent (green | blue | violet, default green): shimmer hue.
|
|
- sweep_at (number, 0.2 to 2 seconds, default 1.2): requested sweep start.
|
|
|
|
Envelope: IN includes clean stillness until sweep_at, then one fixed 0.9s
|
|
sweep. If the mounted duration is too short, the sweep starts earlier and
|
|
compresses only when it cannot fit. HOLD is elastic and keeps the clean end
|
|
state alive with an off-glyph drift. OUT is intentionally zero because the
|
|
treatment returns to ordinary text rather than dismissing it.
|
|
|
|
Mount contract: everything renderable lives inside the template. #root is
|
|
elastic, fills the host box, establishes the container query basis, and has
|
|
no data-width or data-height. The paused GSAP timeline registers under the
|
|
hardcoded text-shimmer key.
