/*
  AARK V2 — shared site chrome: utility bar, header/nav, mobile menu, footer.
  Single source of truth (replaces the v5–v16/v19 override chain formerly
  in styles.css). Loaded on every public page after styles.css and tokens.css,
  so it wins on source order without !important. Uses tokens from tokens.css.
