/* The one build card + its ⋯ menu, sheets and toast (P5 Navigation, 16.10.2026).
   Design: docs/curator-editor/studio-launch/mockups/navigation.html ("Obsidian & Brass", the studio's tokens from
   static/curator-editor/studio.css). Loaded by the Housing Hub and the studio home; every class starts with umb-, every
   token with --umb- so nothing collides with catalog.css (which scopes its own --hs-gold inside .hs-show). */
