- Read-only sessions boot BOTH panels open as collapsed headers (a stored
per-browser choice wins); inspector's default anchor moves to the
top-left, layers keep the top-right stack under the FAB.
- Layer rows follow KiCad's Appearance-pane order: color swatch, eye
toggle, layer name (name click = set active).
- read-only spec: boot-default assertions (open + collapsed + top-left
anchor) in the lock test, chevron expansion in the panels test.
