/* =====================================================================
   Extem — project journey roadmap.
   Same mechanic as the reference 3D road: sticky full-screen canvas
   with a glowing path, scroll-driven camera, cross-fading step cards,
   dots + counter. Falls back to a readable timeline without WebGL or
   with reduced motion. EXTEM water colors. Loads after showcase.css.
