   1. Modern CSS reset
   Deliberately minimal — resets only what causes cross-browser
   inconsistency, preserves useful UA defaults (e.g. focus rings) rather
   than a full Eric Meyer-style wipe, since we re-add accessible focus
   styles explicitly below anyway.

   visible — e.g. "Menu" label on an icon-only toggle button.

   Two widths by design: --nova-container-width for full-bleed sections
   (header/footer bars) and --nova-content-width for the actual reading
   column, matching theme.json's contentSize so block editor and frontend
   agree exactly.
