/* Karty public site — shared stylesheet for every page (site/build.mjs
   writes every page to reference this one file instead of embedding its
   own copy of the same ~250 lines — one cacheable file across the whole
   site beats duplicating it per page, and it means a design tweak is one
   edit here, not N edits across every generated HTML file). Extracted
   2026-10-01 from the original single-page site/index.html; design tokens
   below are unchanged from that version. */
