   Shared device-settings stylesheet
   ──────────────────────────────────────────────────────────────────
   Single source of truth for the radio device "further details" panels
   (M330 / M423 / M503 / M505 *DeviceSettings* components). Hosted in the
   RadioCanvas RCL because it is the in-house static-asset library that
   BOTH apps (SRCTutor.FrontEnd and RadioTutor) already load via
   _content/RadioCanvas/... . Each device component opts in by setting
   Class="device-settings" on its root <MudForm>.

   Design goals (same as the Simulation settings panel refactor):
   - spacing owned by containers (flex + gap), no floats / negative
     position offsets;
   - one density scale via the tokens below — re-scale from one place;
   - self-contained: defines its own tokens, colours and the MudBlazor
     overrides it needs, so it renders identically in either app without
     depending on that app's app.css.
   Selectors are prefixed with .device-settings so they win over the
   legacy global rules in SRCTutor.FrontEnd/app.css and never leak out.
