/* ============================================================
   QCMS Admin — Login Page
   ============================================================
   ADDITIVE stylesheet. Loads AFTER admin-components.css.
   Uses theme tokens defined in theme-tokens.css / theme-light.css /
   theme-dark.css — no hardcoded colors except inside the brand panel
   (which intentionally stays dark in both themes).

   Page structure:
   - .login-page         → fullscreen wrapper
   - .login-shell        → 2-column grid (brand | form)
   - .login-brand-panel  → left side, always dark, marketing/branding
   - .login-form-panel   → right side, theme-aware, the actual form
   ============================================================ */
