 * V22 · THE DITHERED ART LAYER AND THE VIBRANCY LENS
 * Binding spec: V22-DITHER-SPEC.md §0 (broadly visible at rest, lens brings
 * clarity), §1 (seam bands), §4 (lens mechanics, easter egg, document entry).
 *
 * V22.2 (founder, 2026-08-11) REVERSES V22.1's hidden rest: "completely hidden
 * is bad. Keep it at like some low opacity so you can broadly see it, but on
 * hovering your mouse over it, it becomes clear." So the art is part of the
 * page at rest — 12% (`--art-rest`, from the manifest), enough that you can
 * tell there is artwork and make out the moon, the flower banks, the trail —
 * and the lens is an UPGRADE to full vibrancy rather than the only appearance.
 * Which means the art is no longer a pointer-only secret, and everyone gets it:
 * touch, reduced motion and JS-off all render the art at rest and simply never
 * arm the aperture.
 *
 * Every value that belongs to a SCENE arrives as an inline custom property from
 * art-manifest.json (see DitherArt.astro). Nothing below names a file, a size,
 * a framing or a mask: this block only says how a scene behaves, never which
 * scene it is. That is the whole reason a new artwork costs a pipeline run and
 * zero edits here.

 * enhancement, not the artwork. So the host renders everywhere — touch,
 * reduced motion, script off — carrying the rest layer at `--art-rest`, and
 * only the moving aperture drops out (see the two blocks at the bottom of this
