- packages/ui/styles/base.css: add `text-autospace: ideograph-alpha
ideograph-numeric` to html. Native CSS feature (Chrome 119+,
Electron recent) that auto-inserts 1/4em space between CJK ideographs
and Latin letters/numerals. Progressive enhancement — older browsers
ignore the rule silently.
- docs/design.md: update font family table to reflect Inter + CJK system
fallback. Reword font-bold ban rationale to be font-agnostic
(information density / layout rhythm), not Geist-specific.
