Pressing Layout while a band was open gave `?section=layout&band=footer`, so the row for the whole
section led to one part of it. Pressing a section carried whatever the last one had left behind.
Every link built a copy of the current query string and deleted the parameters known to be scoped —
`media`, then `page`, and `band` would have been the third. That is a list of exceptions that has to
grow every time a section gains a parameter, and it fails silently when somebody forgets: the link
still works, it just goes somewhere more specific than it says.
Starting from an empty query string inverts the default. A parameter survives a navigation only if the
link says so, which is one decision at each link rather than a list of everything that must not leak.
So a section row is `?section=x`, and a sub-item is that plus its own `band` or `page`. Nothing else
rides along, including the device and the open tab — both are restored to their defaults by the panel
that owns them, which is where a default belongs.
