/* Agenda — evening / social session card (.programme-item.type-special_event).
   Dinner, reception and gala entries carry the API's own `special_event` type
   since 2026-08-05; before that they arrived as `plenary` and were recognised
   by title keywords in the client (`is-evening`). Declared after
   agenda.plenary.css, which gives both types the full-row layout — here only
   the background differs. An editor's inline colour_override still beats this.

   Colour token stays `--colour-evening`: it is the editor-facing field name on
   the edition blueprint (colour_evening), and renaming it would be a content
   migration for a label nobody asked to change. */
