/*
 * Theme "knooppunt" (ghbexperience.com). Design brief:
 * 1. Concept: the signal box at a railway junction at night. Every choice is a switch, every end of the line a
 *    signal aspect (stop, caution, proceed) with one clear next step. Calm, dark, built to be read on a phone at 3 am.
 * 2. Type: Hubot Sans (variable width and weight: condensed bold for signals, normal width for reading) +
 *    Azeret Mono (signal codes, route numbers, labels). Self-hosted woff2, latin + latin-ext.
 * 3. Palette: night #0e1216, panel #161c22, rail #2b353e, chalk #eef0ea, signal red #ff6a5c (fill #c9372c),
 *    signal amber #f2b43c, proceed green #4cc38a. Text contrast on night >= 8:1.
 * 4. Layout signature: ARCHETYPE interactive decision tree. Home = the board: one question at a time with switch
 *    buttons, a route log, and a mimic panel (SVG track diagram) that lights the route; without JS the whole tree
 *    as nested track lists. A light "test bay" with the GHB test. Deep pages = route sheets with a signal plate,
 *    a track rail of stations and "Next signals" switch cards.
 * 5. Finishing detail: flat signal lamps (no glow) carry meaning everywhere: red = act now, amber = stay alert,
 *    green = before you start; codes like A2 or R4 tie every page back to a place on the board.
