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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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 ticker-takeover" />
|
|
|
|
That writes one file: `compositions/components/ticker-takeover.html`.
|
|
|
|
## Paste it into your composition
|
|
|
|
Open `compositions/components/ticker-takeover.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 |
|
|
| --- | --- | --- | --- |
|
|
| `options` | `faster,smarter,together,everywhere` | string | Comma-separated words shown by the ticker. |
|
|
| `final_word` | `together` | string | Word the ticker locks on and promotes. |
|
|
| `accent` | `green` | `green`, `blue`, `violet` | Color used for the lock flash and promoted word. |
|
|
|
|
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="ticker-takeover"
|
|
data-composition-src="compositions/components/ticker-takeover.html"
|
|
data-variable-values='{"options":"faster,smarter,together,everywhere","final_word":"together","accent":"green"}'
|
|
></div>
|
|
```
|
|
|
|
## Source
|
|
|
|
<Accordion title={`ticker-takeover.html`}>
|
|
|
|
```html
|
|
<!doctype html>
|
|
<!--
|
|
ticker-takeover: a compact ticker rolls through four to six words, locks
|
|
on the selected word with an accent flash, then promotes that word into
|
|
a full-frame headline.
|
|
|
|
Variables:
|
|
- options: comma-separated words shown by the ticker.
|
|
- final_word: the word placed last and promoted.
|
|
- accent: green, blue, or violet lock color.
|
|
|
|
Envelope (fixed IN and OUT, elastic HOLD only):
|
|
IN_BASE = 3.15s. Ticker entrance, accelerating roll, decelerating lock,
|
|
accent flash, and headline promotion.
|
|
HOLD = max(0, D - IN - OUT). The promoted word drifts subtly.
|
|
OUT_BASE = 0.45s. The promoted word fades and rises.
|
|
If D is shorter than IN_BASE + OUT_BASE, IN and OUT compress together.
|
|
|
|
Mount contract: all rendered content lives inside the template. The root
|
|
fills its host without fixed dimensions, and one paused timeline registers
|
|
under the hardcoded ticker-takeover key.
