/* AHS website, Phase B (V2-S13B, app/web2b.py). Linked only while one of the S13B switches is on; web2.css stays the Phase A sheet.
   Dark theme (WEB_V2_THEMES): the S0 surfaces (base #14171B, raised #1C2026, panel #242931), text #E6E9EE / #B1B8C3, the one action
   in safety orange with black text, brass for rules and labels. Every text pair is 7:1 or better (tests/test_web2b.py checks them).
   Motion: one hero sequence (web2-hero.js); nothing loops; prefers-reduced-motion gets the end state. */
