User-caught drift, and it was live in the UI, not just prose: the demo
harness's hand-copied PALETTE_GROUPS enumerated 31 scales — fuchsia and
steel (the two non-Radix scales) never appeared in any demo's
PalettePicker even though PALETTE_SCALES (the const, 33) and the recipe
cascade (paletteScaleDecls maps the const) resolve them fine. Fixed the
two missing entries, typed the groups as PaletteScale[], and added a
dev-time completeness assertion so growing the const without grouping
throws at module load.
Prose swept (the numbers were inherited verbatim from the pre-book
sources, which contradicted their own '33-scale library' headers):
decisions.md color-model row, demo-authoring x4 (incl. the '31-scale
palette' lede), rfc-color-engine x4 (ground-truth + templates
open-question). Where the count was incidental the text now points at
PALETTE_SCALES instead of restating a number.
Guard: docs-check I1 gains the palette count (EN + ES patterns,
~-approximation and type/space-scale exclusions; s-mark added to the
section-number skip). The check line now prints palette=33. This was
the exact class I1 already covered for families/intents/archetypes and
had not been extended to the palette.
