Once a card's preview is drawn, PosterSection shows only the picture: its
title survives in the img alt and the sticker's aria-label. In Poster
Design, a reference gallery, every drawn template therefore went
unnamed on screen (all 14, measured).
PosterWall gains captionUnderPreview (default off): a drawn card keeps its
title under the picture, inside its frame (the frame stacks picture over
caption; the picture takes what the caption leaves, with a zero basis so a
tall sheet never stretches the square frame). Off, a card renders as
before. Poster Design's Styles turns it on.
check:poster-wall-host-seams arm M: off, a drawn card is only its picture;
on, a pending card is uncaptioned and the drawn card names itself. Seen
failing for a caption always shown, never shown, and shown while pending.
The bundles that compile PosterWall are rebuilt.
