/* ==========================================================================
   RACE HOUSE COMMUNITY — v3 "Forza update" HUD theme
   Need-For-Speed-style digital dash aesthetic: near-black cockpit,
   teal primary neon + amber secondary, angular clipped panels,
   digital-readout numerals. No imagery — all CSS/SVG drawn in code.
