/* Papers — the design system for pages.cory.land.
   Ported from the email app that set the house style: pure white canvas,
   zinc neutrals, hairline borders, Geist for chrome, one serif reserved for
   mastheads, and a single blue accent that appears only on live or
   interactive affordances. Pages build from these tokens and roles; a page
   may add a short style block for its own layout, but never new colors,
   new type sizes, or new motion curves. */
