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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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 hw-boil" />
|
|
|
|
That writes `compositions/components/hw-boil.html`, plus 1 supporting file under `assets/fonts/`.
|
|
|
|
## Paste it into your composition
|
|
|
|
Open `compositions/components/hw-boil.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.

/* ---- hw-boil -----------------------------------------------------
|
|
The hand-drawn "boil": jitter that re-poses only every N frames
|
|
(quake + frame-drop style). Pose is a pure function of quantized
|
|
timeline time through a seeded hash — fully seek-safe, renders
|
|
identically on every pass over the same frame.
|
|
|
|
RULES:
|
|
- hwBoil owns x/y/rotation of the boiled element. Entrance/exit
|
|
tweens go on a WRAPPER around it, never the boiled element.
|
|
- One timeline has ONE onUpdate — hwOnUpdate is the dispatcher
|
|
that lets the boil coexist with sweep scalars etc. Register
|
|
every onUpdate-style render through it. */
