   FM overlays on migrated (dash_migrated) pages
   js/fm-app.js appends toasts (#fm-toast-stack/.fm-toast) and dialogs

   <body>. Their styling used to come from bootstrap.css (.modal* chrome) +

   pages, leaving them unstyled (bare dialog at top-of-document, bare toast at
   bottom). Re-provide that styling here: u4-dash.css loads on EVERY dashboard
   page, and BEFORE the v2/bootstrap sheets on non-migrated pages (so those still
   override this — no change there); on migrated pages this is the only source.
   Modal chrome is scoped to .fm-confirm/.fm-modal so it can't affect any other
   element; brand colours replace the dropped v2 hsl(var(--*)) tokens.
