/* Newsfeed polls: the poll attachment card (display + composer preview) and the poll composer dialog.
   Namespaced with .nfp- to avoid collisions; loaded globally via App.razor because scoped .razor.css
   does not load for Client (WASM) components in this app.

   Design intent: a calm, self-contained widget that sits comfortably next to the SharedShow attachment
   and the admin-statistics surfaces. Soft card (hairline border + low shadow), a clear POLL eyebrow,
   tappable option pills before voting, and result bars where the viewer's pick and the leader read at a
   glance. All colour derives from --mud-palette tokens (and the matching -rgb variants for tints) so the
   light and dark themes both work. */
