Capture · Roots: the twelve roots round 1 found

Eleven more roots drop w_full: the docked ActionBar, MessageBubble's
three arms, PromptInput, TitleBar, Tabs, the horizontal Divider with
and without a label, DropZone and Playlist. Their hosts in the crate
are blocks or flex columns. The gallery's docked ActionBar sits in an
items_center column, so the demo gives it the width.

AspectRatio keeps w_full, and AGENTS.md says why: taffy 0.9 follows a
ratio from a set width, not from a stretch, and without one the image
gallery's tiles and the ratio demo collapsed.

Every page and scripted state was shot again at full width and at
280px and compared with the shots from before T44a. Nothing collapsed
or shrank. The mail reader's attachments now wrap side by side, as
their row asks.
