/* Master Control Panel theme -- deliberately a different palette from the
   tenant app's navy/sky/gold (style.css :root) so a master session can
   never be visually mistaken for a tenant session, per PHASE_B_DESIGN.md §2
   and the queue's explicit "never confused" requirement. Reuses every
   structural class from style.css (.card, .btn, .stacked-form, .auth-page,
   .alert-*) by overriding the same custom properties those rules already
   read from, scoped to body.master-theme so it never leaks onto tenant
   pages.

   Links and accents use the tenant app's blues and gold (style.css :root,
   2026-11-02) on the master's own dark surfaces. The dark login console
   keeps its violet: its card sets its own values (auth.css .lp--master),
   and the few rules below that would reach it read logged-in-only values
   (body.master-theme:has(.master-shell)) with the violet as fallback. */
