/* ————————————————————————————————————————————————————————————————
   TermiForge site — single stylesheet, system-font stack, no deps.
   Design principles:
     • Use typography and whitespace for hierarchy; avoid decorative flourish.
     • Stay close to iOS/macOS type conventions so the site looks like an
       extension of the app, not a marketing microsite.
     • Accessible contrast, responsive at every breakpoint.
