   Design language: analog-editorial. Espresso + cream surfaces, a single
   disciplined amber accent reserved for interactive elements, New York / Georgia
   serif display, and a quiet spinning-vinyl motif. Flat, paper-like surfaces —
   depth comes from layered shadow and hairline borders, not glow.

   Display type: New York (Apple system serif) with Georgia fallback — an
   editorial serif, no web-font download. One stylesheet skins every page.
