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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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

# cursor-glyph-trail
|
||||
|
||||
An actor (default: a cursor dot) travels an authored path and deposits small dithered glyphs at its past positions. Each glyph pops in where the actor passed and decays in place; stamps land at fixed arc-length spacing along the path, so the per-second stamp rate scales with the actor's velocity. The jh3yy stamp-and-decay register: the trail is the residue of the motion, fully dissolved before the hold.
|
||||
|
||||
4s authored, elastic HOLD, exit `none` by default.
|
||||
|
||||
## Variables
|
||||
|
||||
| id | type | default | notes |
|
||||
| --------- | ------ | -------- | ------------------------------------------------------------------------------------------------------------- |
|
||||
| `glyphs` | string | `░▒▓+·×` | Stamp charset; one glyph per stamp is chosen by a fixed-seed LCG. |
|
||||
| `density` | enum | `med` | Arc-length spacing between stamps: `low` (4.6), `med` (2.9), `high` (1.8) percent units. |
|
||||
| `path` | enum | `sweep` | `sweep` is an S-curve lower-left to upper-right; `arc` rises over the top; `zigzag` cuts three straight legs. |
|
||||
| `fade` | number | `0.8` | Per-stamp decay window in seconds, clamped 0.3 to 1.5; per stamp varied 0.75x to 1.25x. |
|
||||
| `accent` | enum | `green` | Trail and actor color: green rides `--brand`, blue rides `--accent`, violet rides `--accent-2`. |
|
||||
| `exit` | enum | `none` | `none` holds until the cut; `fade` departs opacity-only; `up` rises out. |
|
||||
|
||||
## Actor slot
|
||||
|
||||
The actor is a slot. Place an inert template anywhere in the HOST page (templates never render, and the runtime wipes the host clip's own children on mount, so the slot lives at document level):
|
||||
|
||||
```html
|
||||
<template data-slot="cursor-glyph-trail-actor">
|
||||
<img src="./assets/cursor.svg" alt="" style="width: 4cqmin" />
|
||||
</template>
|
||||
```
|
||||
|
||||
With no slot, the primitive renders a token cursor dot (accent core, hairline ring, contract tokens only).
|
||||
|
||||
## Mount
|
||||
|
||||
```html
|
||||
<div
|
||||
class="clip"
|
||||
data-composition-id="cursor-glyph-trail"
|
||||
data-composition-src="./cursor-glyph-trail.html"
|
||||
data-variable-values='{"path":"zigzag","density":"high","accent":"blue"}'
|
||||
data-start="0"
|
||||
data-duration="4"
|
||||
data-track-index="0"
|
||||
></div>
|
||||
```
|
||||
|
||||
Elastic root: no `data-width`/`data-height`; it fills whatever box the host clip gives it. Timeline registers under the literal `cursor-glyph-trail` key.
|
||||
|
||||
## Notes
|
||||
|
||||
- Deterministic: the stamp table (positions, times, glyph choices, jitter, sizes, peaks, decay multipliers) is built once at mount from fixed LCG seed `0x67117a11`. Stamps carry no tweens: each stamp's opacity is recomputed on every timeline update as a pure function `f(tl.time() - t_i)` of its table row (two sequential tweens on one property render in direction-dependent order under GSAP seeks), and the actor position is recomputed from `tl.time()` the same way, so eventful seeks (`suppressEvents=false`, the engine's render path) land identical frames in any order and either direction.
|
||||
- Density law: stamps land at fixed arc-length spacing, so faster travel deposits more stamps per second; the shared ease (power2-style inOut) makes the trail thin at the ends and dense through the middle.
|
||||
- Every stamp's decay completes inside IN by construction (`IN = travel + pop + fade * 1.25 + margin`), so the HOLD is truly still: the actor rests at the path end and the field is empty.
|
||||
- The travel ease is one shared function used by both the stamp-table sampler and the per-update actor position, so stamps always sit exactly on the actor's past path.

cursor-glyph-trail: HyperFrames video primitive (product demo / trails)
|
||||
|
||||
An actor (default: a cursor dot) travels an authored path and deposits
|
||||
small dithered glyphs at its past positions. Each glyph pops in where the
|
||||
actor passed and decays in place; stamps land at fixed arc-length spacing,
|
||||
so the per-second stamp rate scales with the actor's velocity. The jh3yy
|
||||
stamp-and-decay register: the trail is the residue of the motion, and it
|
||||
has fully dissolved before the hold.
|
||||
|
||||
The actor is a SLOT. Callers supply content by placing an inert template
|
||||
anywhere in the HOST page (templates never render, and the runtime wipes
|
||||
the host clip's own children on mount, so the slot lives at document
|
||||
level):
|
||||
|
||||
<template data-slot="cursor-glyph-trail-actor"> ... </template>
|
||||
|
||||
With no slot, the primitive renders a token cursor dot (accent core,
|
||||
hairline ring).
|
||||
|
||||
Variables (declared in data-composition-variables below):
|
||||
- glyphs (string): the stamp charset; one glyph is chosen per stamp by
|
||||
a fixed-seed LCG. Default is a dithered block-and-punctuation set.
|
||||
- density ("low" | "med" | "high", default "med"): arc-length spacing
|
||||
between stamps; higher density means tighter spacing.
|
||||
- path ("sweep" | "arc" | "zigzag", default "sweep"): the authored
|
||||
travel path preset.
|
||||
- fade (number seconds, default 0.8, clamped 0.3 to 1.5): the decay
|
||||
window of each stamp; per-stamp decay varies 0.75x to 1.25x of it.
|
||||
- accent ("green" | "blue" | "violet", default "green"): green rides
|
||||
--brand, blue rides --accent, violet rides --accent-2.
|
||||
- exit ("none" | "fade" | "up", default "none"): frame roots own
|
||||
transitions; the default holds the final frame to the last pixel.
|
||||
|
||||
Envelope, fixed IN and OUT with elastic HOLD only (never timeScale):
|
||||
IN_BASE = TRAVEL (2.4s) + pop (0.07s) + fade * 1.25 + 0.05s margin;
|
||||
the actor arrives at TRAVEL and every stamp's decay tween
|
||||
ends inside IN, so the HOLD is truly still
|
||||
HOLD = max(0, D - IN - OUT)
|
||||
OUT_BASE = 0.45s only when exit != none
|
||||
If D < IN_BASE + OUT_BASE, the whole envelope compresses together.
|
||||
|
||||
Determinism: the stamp table (positions, times, glyph choices, jitter,
|
||||
sizes, peaks, decay multipliers) is computed exactly once during
|
||||
synchronous mount from fixed LCG seed 0x67117a11. On every timeline
|
||||
update, each stamp's opacity is recomputed as a pure function
|
||||
f(tl.time() - t_i) of its table row, and the actor's position as a pure
|
||||
function of tl.time(); stamps deliberately carry NO tweens (two
|
||||
sequential tweens on one property render in direction-dependent order
|
||||
under GSAP seeks, which breaks byte-identical frames). No Math.random
|
||||
at runtime, no wall clock, no incremental state, no
|
||||
requestAnimationFrame. Eventful seeks (suppressEvents=false, the
|
||||
engine's render path) land identical frames in any order and either
|
||||
direction.
|
||||
|
||||
Mount contract: the runtime clones only this template. #root fills the
|
||||
host box (no data-width/data-height, container-type: size, cqmin units),
|
||||
is styled via #root only, and registers one paused timeline under the
|
||||
LITERAL "cursor-glyph-trail" key.
