/* Resistro primary-nav — shared across all marketing pages.
   Depends on CSS custom properties from the page: --bg, --border,
   --text, --text-dim, --text-bright, --accent, --accent-dim.
   Breakpoint 1180px matches the widest link-row that still fits on
   a 13" laptop without overlapping the brand. */
