/* =========================================================================
   Advanced Settings page — mobile makeover.
   Massive 7-tab settings page with API keys, integrations, forms, tables,
   toggles, and a lot of coloured info banners. CSS-only pass:
     - Title hidden
     - Sub-nav tabs → horizontal-scroll pill row
     - All multi-column grids stacked
     - Content cards tightened
     - API-key row stacks
     - Coloured banners compacted
     - Any tables → display block cards (per section)
     - Notification toggle rows styled as tidy cards
   ========================================================================= */
