The desktop composite pairs the research dashboard with the grid. This is its
mobile sibling: the monolithic 7-tab research map on top, the same grid beneath,
stacked to scroll. Which one a shell shows is an aspect-ratio choice made at the
SPA level, so neither plugin knows about the other and both stay embeddable.
The grid's own search and filters are ON here. The desktop composite turns them
off because the dashboard header owns those controls and drives the grid through
props; the research map has no such header, so switching them off would leave the
grid with no way to be searched at all.
Composes its children by tag and bundle URL rather than importing their .vue
files. Importing the research map directly would bypass its bundle entry, which
is where its three bundle-private colour strategies, its profile registry, its
Pinia and i18n pair and the RTL text plugin are installed — and losing those is a
runtime defect in a green build, because a thrown setup() removes the subtree
with an empty error.
Add check:composite-srcs, which resolves every nested src against the built tree
and asserts every nested tag is registered. A wrong relative depth is a 404, and
the stack layout swallows a failed section on purpose so one broken child cannot
take the whole stack down — which means the cost of that resilience is a silently
empty band. Negative-tested both ways: breaking the depth and renaming a tag each
fail with the file and path named; restoring returns to pass.
