/* EXIMIA — /ai-systems (v3). Loaded after styles.css + v3.css.
   Concept: "una capa de inteligencia sobre tu operación real". Every scene is a
   black & white Higgsfield photo plus its digital twin (the same frame drawn as
   white lines on black); ai-systems.js wipes from one to the other as the scene
   crosses the viewport. The hero loop does the same with the corridor. Calm by
   design (owner, 2026-09-30): no pinned films, no HUDs, no flashes. */
