Replace the synthetic step-9-at-opacity alpha ramp with a real compositing inverse: each --scale-X-aN is the translucent color that, painted over the scale's background (white for light scales, black for dark, by step-1 luminance), reproduces the opaque solid step N (Radix model). Computed in render-css.ts for ANY theme (base + custom), so alpha is consistent-by-construction with the solid scale and cannot drift. alphaScales opt-in still wins verbatim; non-hex solids fall back to the legacy color-mix ramp. Verified: --scale-purple-a9 = rgb(92 0 173 / 0.6941) over white = #8e4ec6.

Alpha steps (--scale-*-aN) are unconsumed today (only a test + README ref). The step-9-at-opacity synthesis is a valid 'accent-at-opacity' ramp default, not a bug; it is not a Radix-style reproduction of the solid scale. Documented the model, its limitation, and the already-wired alphaScales opt-in in appendColorAlphaScaleDeclarations. A build-time compositing-inverse generator is deferred until alpha is actually consumed.

Token Scope Contract universal — no más excepciones arquitectónicas.
Los 3 componentes que vivían fuera de TSC v2.1 (select, avatar,
toggle-group) ahora están dentro del contrato via dos extensiones nuevas.
TSC v2.2 extensiones (lib/config-types.ts + render-css.ts + config.ts):
- `parts: readonly string[]` en RecipeTokenMultiDeclaration — emite
selectores comma-separados (`[data-{c}-x], [data-{c}-y]`) para
componentes con data-color cascadeado per-part. Consumer: select.
- `composition: { foreignRecipe: { targetSelector, tokens } }` sibling
key — overrides cross-recipe scoped a la cascade del host. Consumer:
toggle-group modifica `--toggle-palette-*` en sus items.
Migraciones:
- select: 3 private `_accent-{track,border,text}` con parts: ['trigger',
'content'] + 7 cascades color:X each. Removed orphan `_accent-solid`
(CSS no consumía).
- avatar: 6 tokens via composite scopes `['variant:X', 'color:Y']` con
matrix helper inline. Badge usa parts: ['badge']. Reemplaza 24 bloques
CSS × 2 partes.
- toggle-group: composition block con 8 palette tokens × 4 colors.
Reemplaza 4 bloques CSS per-color.
Bug toggle-group post-composition (encontrado y arreglado):
Tras la composition migration, el cascade del toggle-group seguía roto
porque los tokens derivados (`--toggle-solid-on-bg`, `--toggle-outline-fg`,
etc.) viven en scope `[data-toggle]`. El `[data-toggle-group-item]` es
sibling (no descendant), así que `var(--toggle-solid-on-bg)` resolvía
undefined. Fix: inlined derivation expressions directamente en
`[data-toggle-group-item]` y sus variant cascades (solid/outline/ghost),
referenciando palette tokens en su propio scope local.
Validador + emisor + contract:
- `validateRecipeComposition` valida el shape `{ targetSelector, tokens }`
y rechaza composition entries con scope='root'.
- `stripCompositionKey` + `emitComposition` separan el pipeline.
- `appendRecipeContractTokens` skip-list para `composition` (no aparece
como fake `--{c}-composition` knob).
- `tokenKeys`/`tokenEntries` helpers en recipe-css-contract.test.ts
filtran composition en todos los iteradores.
Documentación:
- THEMING.md §18 reescrito como "Cobertura universal de TSC". §7
extendido con subsecciones "Multi-part scope" y "Cross-recipe
composition" + ejemplos completos. TOC actualizado.
- eidos/README.md tabla de referencia ampliada con TSC v2.2 + §18.
- CLAUDE.md gana hand-off "2026-05-27 #5" (TSC v2.2 + cobertura universal).
- CONTINUE.md reescrito al estado actual de la sesión.

Single source of truth for typography values that the recipe layer
consumes. The foundation aliases `--font-ui` and `--leading-ui` (read
by ~30 recipe tokens in `lib/recipes/base.ts`) now derive from the
canonical `label` named style instead of carrying duplicate literals:
--style-label-font-family: var(--font-family-primary);
--style-label-line-height: 1.25;
--font-ui: var(--style-label-font-family, var(--font-family-primary));
--leading-ui: var(--style-label-line-height, 1.25);
Chain: typography.ts styles → --style-{name}-* → --leading-ui / --font-ui
→ recipe tokens → component CSS. Editing
`STATIC_TYPOGRAPHY.styles.label.lineHeight` now propagates to every
recipe in one go.
Why not push recipes to consume `--style-{name}-*` directly:
- t-shirt sizes (xs/sm/md/lg/xl) don't map to four semantic buckets
- per-component matices (description/caption/hint) need their own
color / weight / letter-spacing
- ref libraries (Radix Themes, Mantine, MUI, Chakra) all keep
numerical scale for component internals; semantic layer is only for
user-facing typography primitives (`<Text variant="body2">`)
Audit rule R-2.7 (warn): detects literal font-size / font-weight /
line-height / letter-spacing in eidos component CSS. Escape valves:
var(...), numeric identities (0/0px/1), keywords (inherit/initial/
unset), or trailing `/* literal: <reason> */` comment. Current run
flags 6 components with letter-spacing/font-size literals (all
intentional micro-tracking and em-relative; can be annotated case by
case).
Documentation:
- src/uix/eidos/README.md § "Vertebración tipográfica" — two-layer
architecture rationale, alias chain diagram, comparison vs Radix
Themes / Chakra / Mantine / MUI, escape valves
- web/routes/uix/lib/COMPONENT_AUDIT_GUIDE.md § 4.11 — pointer to
R-2.7 + cross-link to the foundation doc
Verified end-to-end in browser at /uix/components/field:
--font-ui → 'Instrument Sans', system-ui, sans-serif
--style-label-font-family → 'Instrument Sans', system-ui, sans-serif
--leading-ui → 1.25
--style-label-line-height → 1.25
computed [data-field-label].line-height → 17.5px (= 14 × 1.25)

`STATIC_TYPOGRAPHY.styles` already defined 11 named typography styles
(hero, h1..h6, body, prose, label, caption, code) but the renderer
only emitted families / sizes / weights — the style entries lived
as data with no CSS reflection.
Extend `appendTypographyDeclarations` so each named style emits:
- `--style-{name}-font-family` → `var(--font-family-{family})`
- `--style-{name}-font-size` → `var(--font-size-{size})`
- `--style-{name}-line-height` → literal or `var(--font-line-height-{size})`
- `--style-{name}-letter-spacing` → literal or `var(--font-letter-spacing-{size})`
- `--style-{name}-font-weight` → `var(--font-weight-{weight})` (or numeric)
- `--style-{name}-color` → `var(--color-{dot.path → dash-path})`
Responsive sizes (e.g. `hero.size = { base: 'xxl', md: 'xxxl' }`)
emit the base value into `:root` and per-breakpoint
`@media (min-width: …)` blocks that override the same variables.
Breakpoint thresholds match `$libs/dom/responsive` (sm: 480, md: 768,
lg: 1024, xl: 1280, xxl: 1536).
`renderStaticCss` now iterates `STYLE_BREAKPOINT_ORDER` after the
main `:root` block and appends one media-query block per breakpoint
that has at least one responsive override. The `indentBlock` helper
preserves indentation inside the wrapper.
`base.css` regenerated. svelte-check 0 errors, `npm run component:audit`
81 / 81 PASS unchanged. This is foundation-only; no components consume
the new tokens yet — that lands in the typography port (Text + Heading
+ Display + Code + CodeBlock + Kbd + Mark + Highlight + Link).
