"""With no project chosen, the gated screens must stay shut on every route.

The redesign shows Cowork and GraphRAG at all times instead of making them
appear and disappear. That is a presentation change only — the gate is the same
`isTabVisible` state as before — so this asserts the gate still actually holds,
and holds for programmatic jumps too, not just for the greyed rail rows.

Runs against an EMPTY home, not a copy of the real one: with any project on
disk the gate is open and the test proves nothing.
