/* ==========================================================================
   Archive Site — plain CSS design system
   Colors, type scale and spacing mirror the original tailwind.config.ts
   tokens 1:1, so re-skinning the whole site means editing the variables
   below rather than hunting through every page.

   Geist/Geist Mono are loaded via <link> tags in each page's <head>, not
   a CSS @import here — @import is discovered late (only after the
   browser has already downloaded and started parsing this file) and
   blocks rendering until it resolves, which is a real, measurable
   performance cost. A <link rel="preconnect"> + <link rel="stylesheet">
   pair in <head>, with &display=swap, lets the browser start the font
   request immediately in parallel and show fallback text right away
   instead of a blank flash while the font loads.
