   PRIVACY FOOTER — clean rewrite 2026-05-30 (Phase 3a v2)
   ----------------------------------------------------------------------------
   Καθαρή λύση: position: fixed στο bottom. Δεν παίζει με grid/flex layout των
   parent containers — απλώς κάθεται πάντα στο viewport bottom.

   Layout rules:
   • Mobile + anonymous: full-width (left: 0 → right: 0)
   • Desktop authorized (≥960px = MudDrawer Responsive Md): left: 240px ώστε
     να μη φαίνεται κάτω από τον σταθερό drawer (240px width)
   • body padding-bottom: 44px ώστε το content να μην επικαλύπτεται από footer

   Hidden σε pages με δικό τους sticky bottom UI:
   • .msg-container (Messages — chat composer)
   • .msg-admin-container (AdminSupport — chat composer)
   • .auth-split (Login — full-bleed split layout με inline footer)
   • .auth-shell (legacy gradient pages: VerifyEmail/ForgotPassword/ResetPassword/
     LoginTotp/Logout — θα αναβαθμιστούν στο Phase 1c)

   MudExpansionPanel refinement (accordions) — same Linear-flavoured aesthetic:
   * Each header: light tinted background + brand accent bar on the left so
     stacked panels read as distinct cards instead of one continuous block.
   * Hover: subtle bg darkening to telegraph clickability.
   * Expanded state: brand-tinted background + accent border-bottom for visual
     separation from the body content.
   * Title: stronger weight so it stands out from the icons/captions inside.
   NOTE: MudBlazor class names are `mud-expand-panel-*` (singular), not
   `mud-expansion-panel-*` — the latter is wrong and silently no-ops. */
