/*
 * The Forge Key — the whitelist legend (js/forge-key.js). MOUNTED 2026-10-06: the "?"
 * trigger sits in every room's `.rooms` nav (shell.js) and the three-step strip sits above
 * the forge on the Satchel (satchel.js). Linked from every room's <head> beside trials.css.
 *
 * Everything is scoped under .fk / .fk-modal / .fk-trigger and uses the tokens declared in
 * trials.css. Per-School hues come from trials.css's `--school-<id>` tokens (forge-key.js
 * sets `--hue` inline, falling back to gold); the tier edges (`--edge`) are metals.
 * Earlier versions: css/_v1-gold/forge-key.css, css/_v2-crystal/forge-key.css.
