/* ============================================================
   STRAAT — concept.html only (v11, "beyond the mountain"). Loaded after styles.css
   for the fonts, the tokens, the menu overlay, the forms and the market chips.
   The hero is a landscape rendered live (terrain.js) that the reader climbs; the
   body is the getvisionairy.com functionality: pinned splits whose left window
   changes with each step, solid blue bars, square corners, dotted paper, a dark
   question block, a footer with the giant wordmark. The loader is inline in the page head.
   Values come from STRAAT (forge3/design): the --st-* tokens arrive in styles.css's generated
   straat:tokens region, and the names below are aliases of them. New values go into
   forge3/design/tokens.json, never here. Rules: forge3/design/DESIGN.md.
   Original implementation, Anthony Meijer / Straat, 2026-09-22 → 2026-09-23 (concept-v11).
