The 720x720 dialog with a 200px side nav becomes a shrink-to-fit modal of
up to 1100x850 with a horizontal icon-tab bar and a full-width content
column. Every tab opens on a hero title with a one-line summary, and one
shared row module supplies the layout language: hairline-separated rows,
right-aligned controls, green iOS-style switches (the one jian Switch call
site gets a success-coloured primary token).
The agents tab lists providers with status pills — connected, not
connected, checking — beside the existing connect and disconnect actions;
the model roster in its hero comes from the shipped presets rather than a
second hand-written list. The MCP tab reshapes into per-CLI toggle rows
with a startup footnote and a custom-config section with a labelled copy
button; the system tab gains a light/dark segmented control writing the
same theme state the top bar toggles. Hit-tests and paints for providers
now share one body-top helper, removing a drifted hand-computed offset.
