   Migrator Admin — styles
   Dashboard UI on the Migrator brand: near-black / off-white neutral with the
   #FF5CD7 pink accent used sparingly. Theme-aware (prefers-color-scheme +
   :root[data-theme]). Tables scroll inside their own containers; numbers use
   tabular-nums; status is encoded as pills.
