/* ============================================================================
   APP Discussions — signed-in dark theme (app.css)
   Shared design system for the in-app pages (Dashboard, Account, What's New,
   project area, Admin, etc.). Login has its own bespoke styles.
   Form inputs are styled via the .field class only (NOT bare input/textarea/
   select selectors) so Telerik RadControls render unaffected.
