/settings/layout/<module> is a URL a person can land on, so with its
module off it now shows the module notice in place, like every module
page, instead of bouncing to the Layout hub without saying why.
Each family of ids must name a surface that exists (nav hrefs, sub-page
directories, section ids, widget ids, derived ids, Settings slugs,
correlation channels). Sub-pages, trend slots and correlation channels
must follow the owner of the types they plot, joined against the
dashboard's summary owners, and a pinned table covers the owners no
join can derive. The replaced per-surface keys and the redirecting page
guard are searched for in source, and the derived route's gate is
compared with the map entry by entry.
Broken on purpose before committing: dropping the sleep sub-page entry,
the mood trend entry or a nav entry, drifting a derived owner, and
reintroducing a per-destination key each fail by name.
Settings sections and Layout groups no longer declare their own module
keys; they ask the surface map. The Insights overview arrange list marks
the breathing, labs changes and cycle blocks unavailable when their
modules are off, as the overview itself would not show them. The rows
stay in the list so a save keeps each block's place.
Appearance ("Darstellung") stacked every module's view and ordering
settings on one long page. Split it into a hub that lists the modules as
navigable rows, each opening its own /settings/layout/<module> subpage
with a back link — the per-module settings move verbatim, no restyling.
The module routes now redirect to those subpages instead of an in-page
anchor, and the in-app cogs link straight to them.
