  RULES:
    1. Never override .nh-collections-hero, .nh-collections-domains,
       .nh-collections-pill, .nh-collections-chip, .nh-sim-card.
       Those live in nh-collections-premium.css. We extend, never fight.
    2. Brand colors: #4776e6 (primary) #8e54e9 (secondary) — not Tailwind indigo.
    3. .nh-collections-domains is repeat(12,1fr). Don't touch it.
    4. All new classes are .nh-hub-* to avoid any collision.
