/* =========================================================================
 * The guest Inner Science Lab (/inner-lab signed out; templates/public/inner-lab.php, assets/js/guest-inner-lab.js).
 * Loaded after guest.css (the g- vocabulary) and inner-lab.css (the reused lab- components: band radiogroup, scope,
 * focus exercise, vault, Ask form). Those lab- components read --lab-* tokens, which inner-lab.css sets on the member
 * page's .lab; here .gil sets them instead, so the guest page needs no .lab class (and none of its global rules).
 * Neural cyan marks the science modules: #22D3EE in Temple Dark, #0E7490 in Temple Dawn (AA on parchment: 5.05:1 on
 * #FBF8F1, 4.64:1 on the #F5EEDF cards); small cyan text on a cyan-tinted fill uses the deeper #155E75 (5.4:1).
 * Phones first: no horizontal scroll at 375px, every control at least 44px, motion off under prefers-reduced-motion.
