   ABOUT PAGE — Polish Layer v1 (2026-05-19)

   Per-page polish overrides loaded AFTER site.css. All rules scoped
   under .about-page so they cannot leak to other routes. Goals:
   tighter section rhythm, equal-height cards, refined hover, gold
   under-heading micro-line, oversight 3→2→1 breakpoint, CTA panel
   surface, mobile cleanup, themed scrollbar, footer transition.
