/* ============================================================
   Orbace Sudoku — re-imagined homepage (R2, site re-imagined v2 §5/§9).
   Ported from docs/os-web-re-imagined721/orbace-site-html-templates/home3.html
   onto css/tokens.css. All classes are `oh-` prefixed and scoped under
   #page-home so nothing leaks into other SPA pages. The functional islands
   (hero replay, Tea Moment widget, ad slots) keep their existing v1-*/og-*
   classes styled by styles.css and the component sheets.
   ============================================================ */

/* ============================================================
   SPA global chrome, re-imagined (unscoped on purpose — this file loads
   after styles.css on index.html, so these override the old tea-green
   chrome on EVERY SPA page: paper-blur header, serif lockup, Inter body,
   forest accents. Matches the static pages' osh-* shell (css/shell.css).
