Finishes the THEMING_AUDIT P3 backlog.
P3-5 (fixed) · appendScaledMetricDeclarations: the `parseFloat(raw) === 0` guard let
non-numeric values (auto / var() / calc()) fall into `calc(x * …)` = invalid CSS. Now
only finite, non-zero numbers are scaled; zero + non-numeric emit verbatim. No change
to the base config output (all values numeric) — pure robustness.
P3-8 (fixed) · index.ts no longer re-exports the raw render-* fns. The public render
API is the ActiveEidos class (gated by assertValid() + active config); ./lib/render-css
stays reachable for internal/tooling use. Redirected the one internal consumer
(active-eidos-config.test.ts) to import renderThemeCss from the module.
Triaged the rest with rationale (audit updated):
- P3-4 deferred · density wins by deterministic source order (stable); the :where(:root)
restructure to also support scoped density is high-cost for a theoretical nit.
- P3-6 already resolved · dispose() routes documentElement via dom (no direct access).
- P3-7 deferred · ActiveEidos reactivity is callback-driven (apply() on pref change) by
design; a full runes conversion is a risky refactor with no bug to justify it.
- P3-9 deferred · orphan _accent forwarders — low-value recipe surgery with cascade risk.
All P3 now fixed-or-decided; only the P2 secondary halves (contract pruning + bare
identifier color validation, both edge-case) remain, deferred as low-value.
check 0 errors · eidos suite green (3 pre-existing words-track failures unrelated).

Tertiary was `gray` — literally the same scale as neutral, and secondary
(slate) is a near-gray too, so the three desaturated roles blurred together.
Per Material 3's tertiary rule (rotate the primary hue ~60deg), tertiary now
uses `indigo`: purple's cool neighbor, saturated enough to be distinct, in a
hue band no intent occupies. Updated the one test that pinned tertiary=gray;
regenerated base.css.

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.
