Ship the base theme's default families (Instrument Sans / Lora / Azeret Mono --
identity unchanged) as self-hosted VARIABLE woff2 (SIL OFL, latin subset, wght
range, preload on primary), so the engine's variable path is exercised by the
default theme, not merely capable. The hand-written themes/fonts.css is retired
(@font-face is config-driven from typography.families[].faces); the static TTF
set under static/fonts/air is removed.
Also close the theming-API gaps so it supports ANY variable font, not just
wght+opsz:
- FontAxes is now a 4-letter-tag map. renderFontFace emits a descriptor per
registered axis: wdth -> font-stretch: min% max%, slnt -> font-style: oblique
(OpenType slnt negated to the CSS oblique sign), alongside wght/opsz.
- TypographyStyle.variationSettings -> --style-{name}-font-variation-settings,
applied by the Text recipe (fallback normal), engaging non-standard axes
(GRAD/MONO/custom) and fixed axis defaults.
Verified: variable faces load with weight ranges + mid-axis rendering; new axis
+ variation-settings emission covered by active-eidos-config.test.ts (99 pass);
npm run check src/ = 9-error baseline (0 new); no default-font regression.
