/*
  Hand-written, mobile-first, dependency-free CSS for the Mileage
  Reimbursement app. See PLAN.md ("Mobile-First UI") for why this exists
  instead of pulling in a full CSS framework: the app has a handful of
  form-heavy screens, and a single-column phone-first layout with large tap
  targets covers nearly all of it. Widen from here as real screens are
  built (trip entry formset, month dashboard table, PDF-adjacent views).
