/* Four Boots — second pass, July 2026.
   Same brand (near-black #191718, pink→orange gradient, Inter body + Roboto display),
   competitor-informed hierarchy and editorial treatment:
   - fluid display type (clamp), tighter tracking, bigger scale contrast
   - system-mono "voice" for kickers, stats, numbering (no new font downloads)
   - gradient rationed to a few moments instead of every band border
   - stats as display-size numerals; numbered services; rule-separated sections
   Still no JS, still accessible: AA contrast, visible focus, reduced-motion respected. */
