/*
 * STLN — public site.
 *
 * Broadcast front door, not a startup landing page. Two things carry the whole
 * design: a real spinning globe painted on a <canvas>, and a wordmark set large
 * enough to be the loudest object on the screen. Everything else — tagline,
 * schedule, platforms, one CTA — is deliberately small counterpoint.
 *
 * Structure still follows tbpn.com: the landing page is one screen, everything
 * else lives on about.html. Resist adding sections.
 *
 * No build step, no external fonts, no network requests.
