/*
  MotoRev brand base: tokens, type, header, buttons, footer. Shared by every
  public page. Landing-only styles live in road.css, content pages in page.css.

  THESIS: MotoRev's landing page is the road itself at night. Every feature is a
  road sign; sections are mile markers. Refuses the floating-phone SaaS layout.
  COLOR ORDER (strict):
    asphalt        the ground, signs are dark reverse plates with white borders
    signal yellow  the one brand accent: CTAs, highlights, lane lines, mile numbers
    protect green  MotoRev Protect only
    emergency red  SOS and alerts only
  MotoRev blue appears inside the app screenshots, not as page chrome.
  FORM: road signage system, grounded list #6, staged as a mile-marker promenade;
  seed b2f3c6f0.
