/* Ferminux Network — public site
   Institutional light. White background, system font stack, one amber accent
   used sparingly, hairline borders, tabular numerals. No gradients, no blur,
   no shadows. Zero external requests.

   Grid discipline: one 1120px container; every titled section shares the same
   rail grid (280px heading rail + content column) so all edges align. The
   live band and the ecosystem directory deliberately span the full container. */
