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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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 mk-background" />
|
||
|
||
That writes one file: `compositions/mk-background.html`.
|
||
|
||
## Add it to your video
|
||
|
||
It runs for 10 seconds at 1920×1080. Paste this into your composition:
|
||
|
||
```html index.html
|
||
<div
|
||
data-composition-id="mk-background"
|
||
data-composition-src="compositions/mk-background.html"
|
||
data-start="0"
|
||
data-duration="10"
|
||
data-track-index="1"
|
||
data-width="1920"
|
||
data-height="1080"
|
||
></div>
|
||
```
|
||
|
||
Move it in time with `data-start`. Put it on a different timeline row with
|
||
`data-track-index`. See [data attributes](/concepts/data-attributes) for the rest.
