/* ==========================================================================
   Tech-futuristic accent layer (Sep 2026). ADDITIVE on the original dark
   design — it keeps the teal glass look untouched and layers on a HUD:
   a faint blueprint grid, monospace precision numerals for data, corner
   brackets on the dashboard panel, tracked technical eyebrows, and a
   restrained teal glow on the live and primary-action elements. Premium,
   not neon. Remove this one <link> to return to the pure original.
