The app said things in two places: sonner's bottom-right toasts and the
custom top-centre chrome. This is the second of those, generalised — a
module-level store anyone can call, drawn as a stack of frosted cards that go
on their own unless raised as persistent, with room for buttons and for a
message longer than a line.
useCustomToast keeps its signatures, so the forty-odd call sites behind it and
handleError are untouched. The component and its store are byte-identical with
the portal's copy and checked by `make design-check`.

The submodule collapse was only half applied: .gitmodules was deleted but
backend/ and frontend/ were still recorded as gitlinks, so none of their
files were tracked. Replace the gitlinks with the real trees.
Also untrack .env (it carried placeholder secrets) in favour of a tracked
.env.example, drop the committed __pycache__, and narrow the blanket *.png
ignore that would have swallowed design assets.
