/* ========================================================================
   GaliVue V5.1.111 — MOBILE WORKSPACE FIXED TOP HEADER
   Presentation-only corrective patch.

   User contract on compact authenticated workspace screens:
   - top workspace header = fixed to the app viewport
   - bottom navigation = remains on the existing V5.1.110 anchored contract
   - only .gv39-dashboard-main content scrolls between them

   This patch deliberately does NOT alter .gv39-mobile-nav positioning.
   No auth/session, API, Worker, D1, R2, billing, project-state, Client
   Selection, Final Delivery, Admin or HERO business logic is changed.
   ======================================================================== */
