/* ============================================================================
   TR-HELPFUL — shared "was this helpful?" feedback widget
   ----------------------------------------------------------------------------
   Promoted verbatim from modules/resource/assets/css/resource-helpful.css,
   where it shipped as `.resource-helpful` / `.resource-helpful-modal`. Every
   declaration below is the value that file carried; the class name moves onto
   the `tr-*` shared namespace required by CLAUDE.md 9.4a.

   Two rules that used to live as page-scoped overrides in single-resource.css
   (`.single-resource .tool-content__sidebar .resource-helpful`) are now the
   `--stacked` modifier, so a sidebar consumer asks for the vertical layout by
   name instead of every page re-deriving it from a descendant selector.

   Consumers: single Resource, single AI Tool, single AI Prompt,
   single Glossary Term.
   Enqueued by tiorai_enqueue_unified_helpful() — single views only.
