/* 刹车挑战 — portrait-first UI over a full-bleed three.js canvas.
   Layout decision (enforced below): on phones the PEDAL ZONE owns the bottom
   ~34% of the screen at full usable width minus the handbrake column; the 3D
   road owns everything above. On short screens (≤680px tall) the chips and gap
   meter shrink first; the pedal never drops below 180px tall. */
