/* KASPA BRASIL — "Aprenda Kaspa em 3D" (/aprenda-kaspa) · 2026-10-07
   Página de capítulos sobre uma cena WebGL fixa (aprenda.js + Three.js 0.169). O texto é HTML de verdade
   (indexável e legível sem 3D); a cena fica atrás, e cada capítulo leva a câmera para uma "estação".

   fixos sobre a cena), Framer/Mistral (painel de controle pequeno sobre a simulação). */
