/*
 * bandAgent website. Plain CSS, one small first-party script (site.js), no
 * external resources.
 * Visual language follows docs/DESIGN.md: system font, semantic colors,
 * brass as the only accent, glass on the navigation bar.
 *
 * The three pills of the logo are the motif: they float behind every page
 * (.backdrop) and pulse like a bar being counted in. Motion is CSS; site.js only
 * fills in where a browser lacks scroll-driven animations.
 * Time-based loops share one tempo (--beat = 128 BPM); scroll-driven
 * animations sit behind @supports, so browsers without them show the
 * finished state. Everything moves only with prefers-reduced-motion:
 * no-preference.
