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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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

whip-pan-cut: HyperFrames video primitive (transitions / bridge)
|
|
|
|
Concept: the louder sibling of cut-the-curve. Scene A whips off laterally
|
|
with directional motion blur while scene B enters in the same direction at
|
|
matched velocity, on a speed-ramp profile (accelerate, fast middle,
|
|
decelerating catch). Two full-bleed content slots (the before-after-wipe
|
|
convention) with token-styled defaults.
|
|
|
|
Wave K, unit K6. Velocity matching is structural: both scenes ride ONE
|
|
strip (B docked one frame-width beyond A along the travel direction) and
|
|
the strip runs a single power3.inOut tween, so the seam velocity is exact
|
|
by construction and the profile is fast-middle with a decelerating catch.
|
|
|
|
Motion blur follows the motion-blur-streak recipe: a directional SVG
|
|
feGaussianBlur (stdDeviation "X 0", horizontal axis only) applied to the
|
|
mover (the strip carries both transform and filter; nothing else is
|
|
filtered, and there is no 3D on the strip for the filter to flatten). The
|
|
blur envelope is CAPPED at 16px and peaks exactly at mid-whip (peak
|
|
velocity), resolving to 0 at both ends: power3.in up over the first half,
|
|
power3.out down over the second, mirroring the strip's inOut velocity. The
|
|
proxy value is re-written on every seek via onUpdate and seeded at setup so
|
|
frame 0 renders sharp.
|
|
|
|
A hairline accent seam rides the boundary between the two scenes; it is
|
|
visible only while the whip runs, so it reads as the frame edge screaming
|
|
past rather than persistent chrome.
|
|
|
|
Slots (see README.md for a worked example):
|
|
- [data-slot="before"]: scene A, on stage at mount. Replace the children
|
|
of this element in your installed copy. Default: a muted token
|
|
wireframe.
|
|
- [data-slot="after"]: scene B, whipping in. Same mechanism. Default: a
|
|
brand-tinted version of the wireframe.
|
|
Direct img/video children of a slot are sized to cover the panel.
|
|
|
|
Variables (declared in data-composition-variables below):
|
|
- direction (left | right, default left): shared travel direction for
|
|
both scenes.
|
|
- whip_at (number, seconds, default 0.25): when the whip starts, relative
|
|
to mount start. Clamped so the whip always completes inside the clip.
|
|
- accent (green | blue | violet, default green): seam hairline and the
|
|
default after art tint. green maps to --brand, blue to --accent,
|
|
violet to --accent-2.
|
|
- exit (none | fade | up, default none): optional departure of the landed
|
|
scene B. Enabling it reserves a short tail window (min(0.35s, 25% of
|
|
D)) after B lands.
|
|
|
|
Envelope (transition profile, cut-the-curve precedent; the catch may still
|
|
be decelerating when a short clip window ends):
|
|
LEAD = whip_at (scene A rests, readable)
|
|
WHIP = 0.55s, power3.inOut, one frame-width of travel
|
|
REST = elastic remainder, dead still on B
|
|
EXIT = 0 when exit is none, else min(0.35s, 25% of D)
|
|
If D < LEAD + WHIP + EXIT, LEAD and WHIP scale down together.
|
|
|
|
Sync point: whip-cut at LEAD + WHIP/2 (peak velocity, 0.53s at defaults).
|
|
|
|
Sound cue: dispatches a bubbling `hf:sfx` CustomEvent with id "whip-cut"
|
|
at peak velocity. This primitive never plays audio.
|
|
|
|
Interruptible springs law (L1): the whip is a single owned tween on one
|
|
strip; a host redirect retargets the same transform channel and GSAP's
|
|
default overwrite preserves current velocity-position state at the
|
|
interruption frame (no snap-to-zero).
|
|
|
|
Mount contract: MOUNTABLE SUB-COMPOSITION. The runtime clones only
|
|
<template> contents; #root fills the host box (inset:0, container-type:
|
|
size), has no data-width/data-height, and registers one paused timeline
|
|
under the literal "whip-pan-cut" key (mount flattening strips
|
|
data-composition-id from the live root). Variables come from
|
|
window.__hyperframes.getVariables().
