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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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

cut-the-curve -- HyperFrames video primitive (transitions / bridge)
|
|
|
|
Concept: a velocity-matched directional hard cut. The outgoing subject
|
|
accelerates along one straight screen vector with power4.in. At peak
|
|
velocity, the timeline swaps identities. The incoming subject starts on
|
|
the far side of the same vector and decelerates to rest with power4.out.
|
|
Matched blur and opacity at the cut conceal the seam.
|
|
|
|
Compiled from the launch write-up for this piece.
|
|
The source identifies the production signature as a single power4 whip,
|
|
with an approximately 1:2 outgoing-to-incoming distance and duration split.
|
|
|
|
Use when: bridging attention and momentum between shots, UI states, cards,
|
|
cursor beats, or scene blocks without requiring object identity to persist.
|
|
|
|
Variables (declared in data-composition-variables below):
|
|
- subject ("cursor" | "card" | "scene", default "cursor") selects the
|
|
simple visual payload used for both sides of the cut.
|
|
- direction ("left" | "right" | "up" | "down", default "left") owns
|
|
both the motion axis and the shared screen direction.
|
|
- cutFraction (number, 0-1, default 0.33) sets the hard-cut point. The
|
|
incoming distance is derived from this fraction so seam velocity stays
|
|
matched. At 0 or 1, the corresponding zero-duration half collapses.
|
|
- blurPx (number, default 12) sets blur at the cut seam.
|
|
- exit ("none" | "fade" | "up", default "none") optionally departs the
|
|
incoming subject at the end. Enabling it reserves a short tail window
|
|
(min(0.35s, 25% of D)) after the incoming subject lands.
|
|
|
|
Envelope (transition profile, no elastic HOLD; T = D minus the exit tail,
|
|
which is 0 when exit is none):
|
|
OUT = T * cutFraction, power4.in
|
|
IN = T * (1 - cutFraction), power4.out
|
|
The default 0.33 split is approximately 1:2 in time. Incoming distance is
|
|
derived from OUT distance and the duration ratio, preserving the same
|
|
approximately 1:2 spatial split and matching velocity at the cut.
|
|
|
|
Sync point: CUT_AT = T * cutFraction, the fixed boundary between OUT and
|
|
IN. It never lands in a HOLD because this profile has no HOLD phase.
|
|
|
|
Sound cue: a short whip cut fires at CUT_AT. The primitive never plays
|
|
audio. It dispatches an `hf:sfx` CustomEvent with
|
|
{ id: "whip-cut", t: CUT_AT } for the scene mix stage to route.
|
|
|
|
EDIT ZONE: change only the subject geometry custom properties in the style
|
|
block when adapting the payload drawings. The vector ratios and the paired
|
|
power4 eases are the mechanic and must remain together.
|
|
|
|
INVARIANTS: outgoing and incoming always share one vector; the identity swap
|
|
happens only at CUT_AT; their blur and opacity values match at that seam;
|
|
exactly one paused timeline registers under the literal id "cut-the-curve".
|
|
|
|
RETIME RANGE: 0.3s to 3s. Retiming changes D only. Never timeScale the GSAP
|
|
timeline and never split the two halves into independently tuned velocities.
|
|
|
|
Mount contract: this is a template-wrapped sub-composition. Everything the
|
|
mount needs, including styles, markup, GSAP, and timeline registration,
|
|
lives inside <template>. #root fills the host box with position:absolute,
|
|
inset:0, and container-type:size. It has no data-width or data-height.
