/* ============================================================================
   settings.css — redesigned admin Settings tab (left sidebar + clean cards).
   Everything is scoped under #tab-settings and uses sx- prefixed classes so it
   cannot collide with the rest of admin.css. Paired with settings.js (the
   sidebar switcher) and the #tab-settings markup in admin.html. The data logic
   (loadSettings/saveSettings/etc.) still lives in admin.js and is reused by ID.
