"""§17 — the seed produces a stack a developer can actually log into.

This file exists because of two real bugs, both found by trying to *use* a
seeded install rather than by reading the code:

1. The seed created ``demo@agy.local`` by writing straight to the database,
   bypassing request validation — while the login endpoint rejects ``.local`` as
   a special-use TLD. The account existed and was unreachable.
2. Even the account that *could* log in belonged to no organization, so every
   screen rendered empty and the demo looked broken.

Neither was caught by the rest of the suite, because every other test signs up a
fresh user at ``@example.com`` and creates its own organization. The seed was
simply never exercised end to end. These tests close that hole.
