Miguel Ángel 9734578e60 feat(registry): bring back the video-primitive moves (#3169) 
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the same unpublished .html path, so it would have shown an empty frame.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.

<!--
Oversized Cursor (actor primitive), mountable sub-composition
concept: a deliberately oversized macOS-style pointer that enters the frame
from off-screen, travels in one continuous glide to a target, taps it (the
click ignites a visible reaction on the target itself), drifts aside during
the dwell, then exits off-screen. One mechanic: a pointer-driven click that
visibly causes something. Family: pointers. Profile: interaction.
compiled-from: spec ready (oversized-cursor SKILL.md, ~/Downloads/oversized-cursor);
actor file mechanics compose (size/look, entry law, tip-targeting, click-ignition,
exit law).
use-when: kicking off a UI scene, igniting a morph/transition/typing run with a
causal click, or carrying the eye across a scene that would otherwise read as
static or stale.
mount contract: this file is a HyperFrames sub-composition, loaded by a host via
data-composition-src, never opened standalone. The runtime clones ONLY the
<template> contents into the host slot (see
skills/hyperframes-core/references/sub-compositions.md); everything outside
<template>, including this <head>, is discarded at render. The root is #root:
elastic, no data-width/data-height declared here, it fills whatever box the host
clip gives it (position:absolute; inset:0). See demo.html for the mount usage
(data-composition-src="./oversized-cursor.html" on a sized host clip).
variables:
cursor_variant (enum light|dark) pointer fill/stroke pairing, pick per scene contrast
target_x, target_y (number, percent of the HOST box) the tip's landing point
click_label (string) label on the target the cursor clicks
exit (enum none|fade|up, default none) optional whole-stage departure during
OUT; the cursor's own off-screen exit always plays (it is the mechanic)
envelope (of data-composition-duration, default 4.2s):
IN 0.00s to 1.17s (fixed) off-screen entry glide (0.85s) then click tap (0.32s)
HOLD 1.17s to D-0.60s (elastic) click ignition plays, cursor drifts aside, then dwells
OUT D-0.60s to D (fixed) cursor accelerates off-screen; with exit fade|up the
whole stage (target included) also departs
sound: one click tap SFX (soft UI click) fires at the click moment, the fixed
offset into IN documented below as SYNC POINT. This file never plays audio: it
only marks the cue's timing for the mix stage to pick up.
