   DigiVal Admin — visual reskin layered on top of the existing
   NiceAdmin/Bootstrap template. Loads after style.css / hover.css /
   bootstrap.min.css and wins the cascade by selector order.

   Colour palette is intentionally UNCHANGED from the original template
   (blue #4154f1, navy #012970, green #2eca6a, orange #ff771d,
   red #dc3545, muted #899bbd, canvas #f6f9ff) — this pass only tightens
   typography, spacing and adds a few shared components (pills, the
   valuation rail, ledger stat cards) built from those same colours.
