/* ============================================================================
   Viral Reader — Presentation Hardening layer (opt-in, brand-neutral)
   ----------------------------------------------------------------------------
   Net-new UX patterns the base theme does not already ship. Everything here is
   token-only (no hardcoded brand colors) so it inherits the active palette and
   BOTH skins (paper / cinematic) for free. Loaded behind the
   `vr_enable_presentation_hardening` filter (default on). See functions.php.

   Deliberately does NOT restyle comments, pagination, search, alignment,
   figcaption, <pre>, footer, gallery, nav-hover, back-to-top, reading progress,
   reading-time or card thumbnails — the base theme already owns all of those.
