   DisclosureIQ Mobile App Shell stylesheet (May 2026)

   Active when html has `diq-app-shell-active` (mobile + streamline root).
   Layers a real native-app feel on top of the existing site:
   - Hides ALL website chrome on mobile (brokerage bar, nav, hero block)
   - Top app bar (56px navy gradient, MS monogram, dynamic title, menu)
   - Bottom tab bar (60px + safe-area, 4 tabs, icons + labels + badge)
   - "You" sheet for install + brand info

   Brand: navy #0F1B2D + gold #C9A961 + cream #FAF7F2. No em dashes.
