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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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

spring-stack-shuffle: HyperFrames video primitive (product demo / physics)
|
|
|
|
A stack of 3 to 5 cards reshuffles on cues: on each cue the card at the
|
|
back of the stack throws over the top and lands at the front with real
|
|
mass (small landing overshoot, the quiet register), while the other cards
|
|
step one slot deeper and give a brief compress-resettle as the flyer
|
|
lands.
|
|
|
|
SIGNATURE (law L1, interruptible springs): when a cue fires while a
|
|
previous shuffle is still in flight, every in-flight card REDIRECTS to
|
|
its new slot preserving its instantaneous velocity. No snap-to-zero, no
|
|
pop. The default cue rhythm (0.9, 1.7, 1.95) deliberately fires the third
|
|
cue mid-throw of the second so the redirect is part of the authored
|
|
choreography.
|
|
|
|
How the redirect stays deterministic and seek-safe: motion is compiled
|
|
at mount into per-card, per-property segment lists (explicit from/to and
|
|
a pure ease function each). A redirect cuts the covering segment
|
|
analytically (value from the ease, velocity from a fixed finite
|
|
difference), truncates it with a renormalized copy of the same curve, and
|
|
continues with a cubic Hermite ease whose start slope equals the cut
|
|
velocity and whose end slope is zero. Nothing simulates: every emitted
|
|
tween is a fromTo with both endpoints authored, so any seek in either
|
|
direction reproduces the same frame.
|
|
|
|
Slots (see README.md for a worked example):
|
|
- [data-slot="card-1"] ... [data-slot="card-5"]: card bodies, front to
|
|
back at mount. Replace the children of a slot in your installed copy.
|
|
Defaults: numbered token skeleton cards. Direct img/video children
|
|
cover the card area.
|
|
|
|
Variables (declared in data-composition-variables below):
|
|
- cards (number 3..5, default 4): how many cards are in the stack.
|
|
- cues (string, default "0.9, 1.7, 1.95"): comma-separated seconds,
|
|
relative to mount start; each cue fires one shuffle. Cues closer
|
|
together than a throw (0.85s) interrupt the flight and exercise the
|
|
L1 redirect. Empty keeps the authored default rhythm.
|
|
- accent (green | blue | violet, default green): active-card ring via
|
|
the contract token map.
|
|
- exit (none | fade | up, default none): frame roots own transitions;
|
|
holds end films.
|
|
|
|
Envelope, fixed IN and OUT with elastic HOLD only (never time-scaled):
|
|
IN = staggered card entrances, back to front, done by ~0.8s
|
|
CUES = clamped into [0.85, D - OUT - 0.9] so every throw lands before
|
|
any exit begins
|
|
HOLD = still after the last landing bump settles
|
|
OUT = 0s for exit none, otherwise 0.45s
|
|
|
|
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 "spring-stack-shuffle" key. Stack geometry is measured
|
|
in px from the mounted root once (cq-unit transform tweens are not
|
|
seek-safe); variables come from window.__hyperframes.getVariables().
