/*
 * BUBLEDUB design system — styles.css
 *
 * Sister brand of RODLEN.COM: the color/line/typography tokens are shared
 * DNA (copied from RODLEN's styles.css), extended with dubbing-service
 * semantics (status colors, progress, pipeline). Dark-first, terminal
 * flavored: IBM Plex Mono for UI, Iceland for display, 1px rules,
 * uppercase tracked labels, square corners everywhere except pills.
 *
 * Fonts are self-hosted (SIL OFL): IBM Plex Mono 400/500 latin+latin-ext,
 * Iceland 400 latin. No Cyrillic subsets shipped — UI copy is EN for now.
