/* ============================================================================
   My Connect Buddy — shared design layer (the MCB look)

   ONE canonical stylesheet, linked into BOTH the organizer portal
   (ConnectBuddy.AdminApp) and the visitor/vendor app (ConnectBuddy.AttendeePwa)
   via a csproj <Content Link>. Edit here and both surfaces move together — two
   copies is exactly how they drifted apart.

   Load order (index.html): MudBlazor.min.css -> cb-design.css -> app.css
     - after MudBlazor so we can normalise its stock component look
     - before app.css so each app can still override locally

   PORTED from My Chamber Buddy's AdminApp (the family blueprint), not invented:
   values, gradients, easing and the signature devices are taken verbatim so the
   Buddies look like siblings. Two deliberate corrections to MCB are marked FIX.

   Section 3 matters most. Screens get reworked in a later pass, so this layer is
   written to make UNTOUCHED MudBlazor components already read as My Connect
   Buddy — every screen improves without being edited.
