Ten catalog ids carry `mockupNever` (kicker-above-heading, icon-tile-stack,
gradient-text, ai-color-palette, cream-palette, nested-cards, dark-glow,
pulsing-dot, identical-cards, hero-metrics) and lib/design-catalog.ts exports
their deduped plain-English names as MOCKUP_NEVER_NAMES. briefToPrompt() in
the design binary appends "Never: <names>." before its fixed tail, so `$D
generate | variants | evolve` stop reaching for purple gradients, icon tiles,
and cream defaults before the comparison board opens. The binary still
bundles (`bun build --compile design/src/cli.ts`); ./setup rebuilds it.
design-html's Never-include list now covers every mockupNever id (kicker /
icon tile, hero metric rows, gradient text, cream palette, nested and
identical cards, glow and pulsing dots), each line tagged with its catalog
ids; test/design-catalog.test.ts pins the exact ten flags, the deduped names,
and that the template list is a superset. New design/test/brief.test.ts pins
the prompt shape.

lib/design-catalog.ts is the single source of truth for gstack's design
anti-pattern vocabulary: the 11 legacy blacklist lines (verbatim, flagged
`legacyBlacklist`), every one of impeccable's 61 registry ids with gstack
prose, tier, impact, confidence, grep heuristic, and /impeccable handoff,
plus the gstack-only tells the LLM pass judges (hero metrics, identical
cards, glassmorphism, missing states, unthemed browser surfaces, ...).
`impeccableId` is set only when the id exists in the registry fixture, and
`renderCatalog({style:'ids'})` brackets an id only then, so rendered prose
never shows an id the detector cannot emit. Role-scoped font lists
(OVERUSED_FONTS_DISPLAY, BANNED_FONTS, FONTS_BODY_UI_OK, FONTS_MONO_OK,
FONTS_VERIFIED_FREE) live beside the entries.
scripts/resolvers/constants.ts now derives AI_SLOP_BLACKLIST from the
catalog. Generated output is byte-identical (bun run gen:skill-docs is a
zero diff). Pure module: no I/O, no scripts/ imports, loading prints
nothing, so bin/ can import it at runtime on every host.
