/* ============================================================================
   eugeny.css — Design system & production stylesheet for eugeny.com
   ----------------------------------------------------------------------------
   "Measured, not marketed." A publication, not a startup landing page.

   This stylesheet codifies the established brand language of Eugeny — the
   sovereign European AI built by Fornace — and scales it from a single hero
   page to a full multi-page site. It is self-contained: only system fonts,
   zero external requests, no build step. It works on a plain file:// open.

   Sections:
     01  Reset & base elements
     02  Design tokens (:root)
     03  Layout primitives (.wrap, section rhythm)
     04  Typography
     05  Site navigation — sticky bar + CSS-only mobile menu
     06  Hero, eyebrow, lede, hero-note
     07  Section head (split .72 / 1.28 grid)
     08  Score grid (absolute predictions)
     09  Proxy cards (--fill bars)
     10  Diagnostic grid (dark ink panel)
     11  Facts definition list
     12  Warning callout
     13  Footer
     14  Page header (eyebrow + title block)
     15  Article prose (max ~680px measure)
     16  Card grid (3-up -> 1-up)
     17  Data table (benchmarks / evidence)
     18  Stat row
     19  Generic definition list
     20  Callout / note (left signal border)
     21  Tag / pill
     22  Timeline / numbered steps
     23  Two-column comparison
     24  Code block
     25  CTA link
     26  Run-status dot
     27  Responsive breakpoints (820px, 520px)
