- BrowserPreview's frame strip scrolls sideways, so every frame stays in
reach in a narrow card
- ArtifactPanel's header wraps: the title keeps label_width, the controls
ride in one group that wraps inside the box
- tests: a_narrow_strip_scrolls_to_its_last_frame,
a_narrow_panel_wraps_its_header
- AGENTS: everything works at 280px
- BrowserPreview: the address with a lock and a spinner while it loads, the
host's frame shown, and the frames so far along the foot as Tab stops;
ScreenshotStream is that strip
- ComputerUseViewer: the host's frame, a ring where the agent points that
rings again at each new point, and what it does there
- LivePreview: the host's page under its address, with reload
- ArtifactPanel: title, versions through chat::BranchNavigator, Preview and
Source when it has both, copy and download; it fails loud with neither
- gallery: frames cut from the gallery's own pages; one asset! macro in
main.rs replaces three copies
