Paul BakausandClaude Opus 4.8 1d5d745823 Make theme switcher three-way (auto/light/dark)
Default is "auto", which inherits from the OS via prefers-color-scheme
and follows it live. Clicking cycles auto → light → dark → auto; the
explicit choice persists in localStorage while auto stores nothing.

The toggle shows the active preference (half-circle / sun / moon) keyed
on a new data-theme-pref attribute, so "auto" is its own visible state
rather than collapsing into whatever the OS resolved to.

// next reload without anyone having to update prose. data-token-value on a
// swatch field reads one token; data-type-scale on a spec line composes a
// "family · weight · size · line · tracking" line from the matching token
// family. Mono and body scales don't have a tracking token; the helper
