/*
 * fuse.css — Fusion Lab (route /fuse, js/pages/fuse.js).
 * 2026-09-10 redesign to a 3-column craft screen per a user reference
 * (AFK-Journey-style artifact screen): a left material rail, a center
 * "fusion chamber" (3 slots as a triangle around a predicted-result core +
 * a chance meter + an effect blurb), a right stage with a big result orb
 * and an E→U grade ladder, and a floating bottom-right action cluster.
 * Cream-on-tan palette kept. The full-viewport "fusion ritual" overlay
 * (.fuse-anim-* / .fuse-result-* / .fuse-used-* below) is unchanged.
