-# ordered-dither-pass
-
-Wave M experiment (texture / transitions). Bayer-matrix ordered dithering
-quantizes a slotted scene: the source is rasterized once at mount to a
-reduced-resolution buffer (one dither pixel is about 3 display px, blitted
-with image smoothing off), and every frame re-derives each output pixel
-from (source pixel, Bayer threshold, the animated dither amount). With
-direction `in` the image emerges from pure 2-tone noise (theme bg vs
-accent) into posterized color and finally clean; `out` runs the ramp in
-reverse and holds the noise. Ordered, parallel, frame-independent; never
-error diffusion. 3.5s authored, elastic HOLD (never time-scaled).
-
-## Mounting
-
-```html
-<div
-  class="clip"
-  data-composition-id="ordered-dither-pass"
-  data-composition-src="./components/ordered-dither-pass.html"
-  data-variable-values='{"matrix":"8","levels":3,"accent":"blue"}'
-  data-start="0"
-  data-duration="3.5"
-  data-track-index="0"
-></div>
-```
-
-## Scene slot
-
-The source scene is a slot. Place an inert template anywhere in the HOST
-page:
-
-```html
-<template data-slot="ordered-dither-pass-scene"> ...scene... </template>
-```
-
-The slot is rasterized through an SVG foreignObject snapshot, so content
-must be self-contained: inline styles or rules carried by host `<style>`
-tags (both are copied into the snapshot), data-URI images only, system or
-already-active fonts. External resources do not load inside a snapshot.
-A missing slot falls back to a token monogram tile rasterized
-synchronously from contract tokens.
-
-## Variables
-
-| id        | type   | default | notes                                                                                                |
-| --------- | ------ | ------- | ---------------------------------------------------------------------------------------------------- |
-| matrix    | enum   | 4       | Bayer matrix size: 2 coarsest crosshatch, 4 classic, 8 smoothest grain.                              |
-| direction | enum   | in      | in resolves noise to clean; out dissolves clean to noise and holds it.                               |
-| levels    | number | 2       | Quantization levels per color channel during the dithered phase (2-6).                               |
-| accent    | enum   | green   | Light tone of the 2-tone noise phase: green maps to --brand, blue to --accent, violet to --accent-2. |
-| exit      | enum   | none    | none holds the final state (frame roots own transitions); fade or up add a 0.45s departure.          |

-## Choreography
-
- 0.00s: the field fades up over 0.25s in its start state (pure Bayer
-  noise for `in`, the clean source for `out`).
- 0.40s: one scalar dither amount ramps across 1.6s (power1.inOut). For
-  `in`: contrast emerges under the dither first, then the dither releases
-  into the clean source over the last stretch of the ramp; the noise
-  phase reads as a bg/accent duotone, the middle as posterized color.
- 2.00s: the ramp lands.
- HOLD: truly still (clean for `in`, pure noise for `out`), elastic with
-  the clip duration.
-
-Sync point `ramp` fires as the amount starts moving; align SFX to it.
-
-## Determinism
-
-The source buffer (a detached ImageData copy), the Bayer threshold table,
-and every resolved color are fixed once at mount. One anchor tween spans
-the full duration and the timeline's onUpdate rewrites one reused
-ImageData end to end from those tables and the current time, then blits
-it scaled with smoothing off. Stateless per frame: no Math.random, no
-wall clock, no incremental state, so eventful seeks (suppressEvents
-false) land identical frames in any order and either direction. The
-no-slot monogram raster is drawn synchronously before the timeline
-registers; a slotted raster arrives from the snapshot decode (page-load
-scale, before capture begins) and repaints the current frame, after
-which all frames are pure f(t).
