/* ============================================================================
   CLASSIC THEME — "ATC Green" (2026-06-03)
   ----------------------------------------------------------------------------
   The Classic theme loads site.css *standalone* (data-theme="site", no overlay
   file — the other themes @import site.css then override). Historically its
   palette was just the light defaults in :root above, but every page ships a
   hardcoded inline `style="background:#0f172a;color:#f8fafc"` on <body>. That
   combination produced near-white text on white (--surface) cards and dark/
   invisible section headers — see the screenshots in /screenshots.

   Original design intent for Classic was a green-phosphor ATC console:
   monospace type, bright readable green text on a dark green-black field.
   This block restores that intent.

   SCOPING: everything is scoped to [data-theme="site"]. That attribute is only
   present when Classic is the active theme (theme-selector.js sets it on <html>
   and <body>). When any OTHER theme is active its own data-theme value is set,
   so none of these rules match — no bleed into Dark/Neon/Horizon/Windows, and
   the bare-:root light defaults still drive the no-JS / auth-page fallback.
