/* ═══════════════════════════════════════════════════
 *  BB News Aggregator — Front-End Styles
 *
 *  Design philosophy: "News Without Political Noise"
 *  ─────────────────────────────────────────────────
 *  Political news = noise. Boulder Bubble filters it.
 *
 *  Visual language:
 *  • Cool-grey background tint (vs Plugin 1's warm white)
 *  • Slightly muted text (distilled, calmer than typical news)
 *  • Source badges in brand colors — the only vibrant elements
 *  • Featured articles "surface" from the noise — warm accent
 *  • Filter bar as an editorial control — you choose what to see
 *
