/* GHAN — ghan.io
   The original GHAN identity, rebuilt on a static, server-rendered page.
   Palette and type are lifted from the previous site's stylesheet, not
   reinterpreted: --eden/--leaf greens, the bone/white paper stack, Syne
   ExtraBold display, DM Sans body, JetBrains Mono for numbers.

   Constraint that shapes everything here: no JavaScript. The technical-GEO
   bundle measures the static response, so the particle field, the hover
   states and the section rhythm are all CSS. */
