/* ============================================================
   CROSSVINE.AI - main.css  (v2 "builder bold")
   Design language: chunky builder-brutalism. Thick borders,
   hard block shadows, hazard stripes, marker highlights.
   One typeface (Bricolage Grotesque) doing all the work through
   weight and scale. Whimsy lives in geometry and color, never
   at the cost of legibility.
   Rules: semantic tokens only in components; no third-party
   requests; SVG-only icons; WCAG AA; no em dashes in copy.
