/* =============================================================================
   ControlF12 — site design system  ("Backlit keyboard")
   Bespoke stylesheet. NO framework. Component classes only (BEM-ish).
   Aesthetic: dark machine-room console — deep navy lifted straight from the
   CF12 keycap logo, blueprint hairlines, mono labels, folio numerals, one
   electric-cyan "backlight" accent. Keycaps are the recurring motif: buttons
   press, product badges are function keys.
   Sibling system: tenderobot.com "Editorial briefing" (paper-light). Same
   editorial discipline — eyebrows, folios, hairline panels — inverted to ink.
