 - Artwork (Radarr posters, Plex thumbs) is relayed through
   `/api/widgets/{id}/image?u=...` - the browser cannot reach the internal host,
   and the relay only ever fetches from that widget's own origin.
+- Calendar cards always name the show, not just the episode: Sonarr's calendar
+  items carry only `seriesId` plus an episode `title`, so the request asks for
+  `includeSeries=true` and reads the name off the nested `series` object (Radarr
+  ignores that parameter). Plex episodes take the show from `grandparentTitle`
+  (`parentTitle` is the season), skipped when it repeats the episode title.
 - `severity` is notice-only: `urgent`/`heads-up`/`info` tints the card edge, the
   chip, and the icon on Home. Setting it on a live widget is a validation error
   (live rows have no severity to sort by).
