   Signal Theatre — Component Stylesheet
   Self-contained styles for the .ecp-* Signal Theatre component.
   Drop this file in any page that uses SignalTheatre.js.

   Design tokens are consumed from the host page's :root if they
   exist, with safe fallbacks scoped inside .ecp-wrap so the
   component works stand-alone too.
