/* =============================================================
   Communities Surveys — styling for:
     • CustomFieldFormRenderer (shared renderer, edit + read-only)
     • CreateSurveyWizard + WizardStep* + WizardListOptionsEditor
     • SurveyPost feed card (with PreviewMode) — includes the answered-state
       expander panel (compact badge + collapse/expand + skeleton shimmer)
     • SurveyResponseModal (fill-in)

   All colors respect the Communities CSS-variable contract:
     --community-primary, --community-accent  (per-community branding)
     --text-primary (#1f2937), --text-secondary (#4B5563)  (WCAG AA fixed)

   Touch targets ≥ 44px where interactive. Focus outlines preserved.
