   LC Dialog + Toast — shared modal/toast engine styles
   JS: dist/assets/js/lc-dialog.js (exposes window.SET)
   Design tokens: --b-* (see lc-design-system.css)

   Extracted 2026-07 from settings.php's inline <style> block
   (originally ported from tools.php) so any authenticated page
   can use window.SET.dialog()/.toast()/.loading() with the same
   look, not just Settings.
