/* ============================================
   MOTOR INCIDENT REPORT — MOBILE-FIRST STYLES
   Brand: #ff6600 orange · #1c1740 navy
   ============================================
   Strategy: base styles target a 320–480px phone.
   min-width breakpoints progressively enhance:
     · 640px : roomier fields, 3-col cards
     · 960px : two-column shell with sidebar stepper,
               in-flow nav (replaces sticky bottom)
   ============================================ */
