Owner polish pair before the settings milestone:
- Model menu: arrows walk the filtered results (clamped, no wrap) while
focus stays in the search field; Enter picks the walked row or, with no
walk yet, the first result; typing resets the walk; click and Enter
share one pickModel path; walked row gets a muted ring + scrollIntoView;
cheat-sheet display entries added.
- Graph: window resizes re-anchor the camera so the world point under the
pre-resize viewport center stays under the new center — the graph stays
visually still while scaling (was top-left pinned). viewW/H tracked in
syncSize; re-anchor applied through the zoom behavior (persistence and
card-dismiss unchanged); kFit refresh as before. Pixel-verified: 7/7
center samples identical across a 300x200 shrink.
