/* ============================================================================
   EduQueue Theme v2  — brand facelift for the authenticated app shell.

   SAFE BY DESIGN:
   - Loaded AFTER background-override.css so it can win the cascade.
   - Every rule is scoped under `body.theme-v2`; with the flag off this file
     is inert (no selector matches), so the app renders exactly as before.
   - Pure skin: retargets EXISTING shell selectors only. No markup, JS,
     form-name, DataTables-init, or endpoint changes.
   - No !important escalation: the legacy overrides in main.css / customize.css /
     background-override.css are gated to `body:not(.theme-v2)`, so this file wins
     by honest specificity. The single remaining !important (.text-primary) only
     beats Bootstrap's own utility !important.

   Preview one page:  append ?theme=v2 to any app URL.
   Enable globally:   config APP_THEME_V2 = True  (or env APP_THEME_V2=true).
   Turn off:          remove the flag — instant, total revert.
