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 The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame.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

# stop-motion-cadence
|
||||
|
||||
The stepped-time law as a demo primitive (Wave M10 experiment). ONE driver quantizes timeline time FIRST, `ts = floor(t * fps) / fps`, and `ts` feeds ALL motion: four token paper-cut shapes throw-and-land in sequence at the quantized cadence, each squashing on its landing hit and recovering over the next steps, with a 2-frame boil jitter on edges (seeded per boil window, stable within it) and sparkle accents living exactly 2 or 3 steps on each hit, frame-alternating big / small-rotated like a drawn twinkle. Reference: the MotionMarkus stop-motion sheets.
|
||||
|
||||
4s authored, elastic HOLD (the boil keeps breathing through the hold; `boil: off` holds dead still), exit `none` by default.
|
||||
|
||||
## Variables
|
||||
|
||||
| id | type | default | notes |
|
||||
| -------- | ---- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
|
||||
| `fps` | enum | `10` | Stepped-time cadence: `8`, `10`, or `12` frames per second. |
|
||||
| `boil` | enum | `on` | 2-frame edge jitter hashed from `floor(step / 2)`. `off` gives a dead-still settle. |
|
||||
| `accent` | enum | `green` | Lead shape color: green rides `--brand`, blue rides `--accent`, violet rides `--accent-2`; the other shapes take the remaining two tokens in rotation. |
|
||||
| `exit` | enum | `none` | `none` holds until the cut; `fade` departs opacity-only; `up` rises out. |
|
||||
|
||||
## Mount
|
||||
|
||||
```html
|
||||
<div
|
||||
class="clip"
|
||||
data-composition-id="stop-motion-cadence"
|
||||
data-composition-src="./stop-motion-cadence.html"
|
||||
data-variable-values='{"fps":"8","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 `stop-motion-cadence` key.
|
||||
|
||||
## Notes
|
||||
|
||||
- The law: quantize before evaluating. Every hit is an integer step index (`landStep = round(t_land * fps)`), squash is a per-step envelope over `step - landStep`, boil seeds hash `floor(step / 2)`, sparkles are visible iff `0 <= step - landStep < life`. Because all state derives from the quantized driver, eventful seeks land identical frames forward, reverse, or shuffled.
|
||||
- Squash uses `transform-origin: 50% 100%` so shapes compress into the floor contact; contact shadows grow and darken as each shape nears the ground.
|
||||
- Deterministic: the jitter hash is a sin-fold over integer indices; no Math.random, no wall clock, no incremental state. Stage size is measured once at mount; per-update writes are transforms and opacity only.
|
||||
- If the mount duration is shorter than the 3s choreography, the throw times compress together, but the fps grid itself never scales; the cadence is absolute.

stop-motion-cadence: HyperFrames video primitive (time law, Wave M10 experiment)
|
||||
|
||||
The stepped-time law as a demo primitive. ONE driver: every frame the
|
||||
timeline time is quantized FIRST,
|
||||
|
||||
ts = floor(t * fps) / fps
|
||||
|
||||
and ts feeds ALL motion. Four token paper-cut shapes throw-and-land in
|
||||
sequence at the quantized cadence, each squashing on its landing hit
|
||||
(transform-origin at the ground contact) and recovering over the next
|
||||
steps. A 2-frame boil rides every shape's edges: jitter offsets are
|
||||
hashed from the boil frame index floor(step / 2), so they are stable
|
||||
within a 2-frame window and pure functions of time. Sparkle accents
|
||||
live EXACTLY 2 or 3 steps on each landing hit, frame-alternating big /
|
||||
small-rotated like a drawn twinkle (per the MotionMarkus sheets).
|
||||
|
||||
Because every hit is defined by an integer step index derived from the
|
||||
quantized driver, seeks land identical frames in any order: forward,
|
||||
reverse, or shuffled evaluation of the same t produces the same step,
|
||||
the same boil seed, the same sparkle state.
|
||||
|
||||
Variables (declared in data-composition-variables below):
|
||||
- fps ("8" | "10" | "12", default "10"): the step cadence.
|
||||
- boil ("on" | "off", default "on"): the 2-frame edge jitter. Off
|
||||
gives a dead-still settle.
|
||||
- accent ("green" | "blue" | "violet", default "green"): the lead
|
||||
shape's color; green rides --brand, blue rides --accent, violet
|
||||
rides --accent-2 (the other shapes step down in value, not hue).
|
||||
- exit ("none" | "fade" | "up", default "none").
|
||||
|
||||
Envelope, fixed IN and OUT with elastic HOLD only (never timeScale):
|
||||
IN_BASE = 3.0s (all four shapes landed and recovered)
|
||||
HOLD = max(0, D - IN - OUT); the boil keeps breathing through the
|
||||
hold (that is the register), boil off holds dead still
|
||||
OUT_BASE = 0.45s only when exit != none
|
||||
If D < IN_BASE + OUT_BASE the choreography compresses together; the
|
||||
fps grid itself never scales (the law quantizes absolute time).
|
||||
|
||||
Determinism: no Math.random, no wall clock, no incremental state; the
|
||||
jitter hash is sin-fold on integer indices. Stage size is measured once
|
||||
at mount; per-update writes are transforms and opacity only, all
|
||||
recomputed from tl.time().
|
||||
|
||||
Mount contract: template-wrapped; #root fills the host box (no
|
||||
data-width/height, container-type: size, cqmin units), styled via
|
||||
#root only; one paused timeline under the LITERAL
