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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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

|
per-word-rise: HyperFrames video primitive (text effects / reveal)
|
|
|
|
Words, or characters through the split variable, rise into place with a
|
|
controlled cascade and a small blur-to-sharp settle. Each unit lands with
|
|
a short overshoot-free settle tail (the final few pixels glide in over the
|
|
closing frames instead of stopping dead), then the finished line holds
|
|
truly still until the frame cuts (exit none) or departs with the optional
|
|
exit variable.
|
|
|
|
Variables:
|
|
- text (string, default "WORDS IN MOTION"): displayed text.
|
|
- split (word | char, default "word"): animated unit size.
|
|
- cues (string, default ""): comma-separated seconds (from mount start)
|
|
for each unit's landing. Empty keeps the authored cascade rhythm.
|
|
- accent (green | blue | violet, default "green"): text color.
|
|
- exit (none | fade | up, default "none"): optional departure.
|
|
|
|
Envelope, fixed IN and OUT with elastic HOLD only:
|
|
IN_BASE = 1.45s, the full staggered rise and sharp settle (cues can
|
|
stretch the rise phase past IN_BASE when they land later)
|
|
HOLD = max(0, D - IN - OUT), truly still: no drift
|
|
OUT_BASE = 0.50s staggered departure when exit is fade or up, 0s when
|
|
exit is none (the default: the line holds until the cut)
|
|
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, has no data-width or data-height,
|
|
and registers one paused timeline under the literal per-word-rise key.
