/* ============================================================
   ATS Holidays — design system
   Mobile-first. Breakpoints: base = phone, >=768px tablet, >=1024px desktop.

   Philosophy: this is a tool people use all day to read numbers. Clarity beats
   decoration — restrained colour, strong typographic hierarchy, soft elevation
   instead of hard borders, and motion only where it explains a change.
