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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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.

headline-slam: HyperFrames video primitive
|
|
|
|
One headline scales down from 1.6 to rest with expo.out weight. Its landing
|
|
drives a deterministic three-frame stage shake, followed by a quiet drift
|
|
and a fast upward exit.
|
|
|
|
Variables:
|
|
text: headline copy
|
|
accent_word_index: zero-based word index to color, out of range colors none
|
|
accent: green, blue, or violet accent color
|
|
shadow: drop shadow under the headline, on by default
|
|
|
|
Envelope, fixed IN and OUT with elastic HOLD:
|
|
IN_BASE = 0.72s, headline slam and three-frame impact shake
|
|
HOLD = max(0, D - IN - OUT), one subtle drift cycle
|
|
OUT_BASE = 0.46s, headline whips upward out of frame
|
|
If D is shorter than IN_BASE + OUT_BASE, IN and OUT compress together.
|
|
The timeline is never time-scaled.
|
|
|
|
Mount contract: the runtime clones only this template. #root fills the host
|
|
box, establishes the container query basis, and has no data-width or
|
|
data-height. One paused timeline registers under the literal headline-slam
|
|
key.
