/* ============================================================
   DS VideoArt: Showcase ("choose a tier, watch it get built live")
   Lives on top of style.css. This page gets its own energetic
   identity instead of the main site's cinema-red: a "blueprint /
   construction" system, vivid electric-orange on near-black, since
   this page is a skills demo, not a video-brand page.
   Adds:
   1) the tier-picker screen
   2) the live build sequence (blueprint -> materialized section)
   3) the demo stage, whose skin is swapped live via [data-style] on
      .demo-stage: every component below reads --sx-* variables only.
