   STAFF MANAGEMENT MODULE
   Every selector is scoped under .stf-page so it cannot affect
   other pages. Icons: MDI. Base UI: Bootstrap 5.

   NOTE ON BUTTON COLOR: .btn-primary / .btn-outline-primary are
   deliberately NOT recolored here - they keep Bootstrap's own
   default (bg-primary blue). Only sizing/spacing is tuned below.
   Tweak --stf-offset if your app top bar is not 64px tall.
