- Deleting an identified account whose security can't be read (the
instance out of reach) says so and deletes nothing; it went on to a
deletion by the session alone, refused for an account with a password,
and the person saw a spinner, then nothing. A refusal still leaves the
session's own deletion.
- InstanceChoice's sharesStorage is required, so no app leaves it out and
removes a folder another instance uses.
- A PasswordUnlock forgotten is spent: its secrets read again fail
(StateError) rather than make a proof or a wrapping of zeros.

What the app sends an instance (the proofs that sign in, the keys'
wrappings, every request a session carries) must not be read or changed on
the way, so an instance is reached over HTTPS, or over plain HTTP only on
this machine (localhost, 127.0.0.0/8, ::1), as Jellyfin servers are. An
address over plain HTTP elsewhere is refused before anything is sent there.
One kept from before is never opened: the app says why, and offers another
instance or removing it from the device, never dropping it silently.
Development builds still use their own instance over HTTP (an emulator
reaches the developer's machine as 10.0.2.2); releases never.

An operator's DATA_LOCATION and BACKUP_LOCATION may name a subdivision
(ISO 3166-2, US-CA, DE-BY) besides the EU or a country. The app adds
"(EU)" to a member country and the country to a subdivision ("Germany
(EU)", "California, United States", "Bavaria, Germany (EU)"), in
English and German, and shows the most specific flag there is: a
subdivision's own where the flag package has one, else its country's.
Subdivision names come from Unicode CLDR 48.2 (tool/subdivision_names.py),
bundled with their licence, which the app registers.

What every Halkyon app's shell needs, taken from Halkyon Learn's and set
on halkyon_base's client: the instances a device keeps an account on,
the first start's tiles and where an instance keeps people's data, the
account switcher; signing in anonymously, with GitHub or an email code,
switching person and the start screen; the gates that build an app's
dependencies per instance and per person; and the sync service with its
status, Settings card and banner. Texts of its own in English and
German take the app's name; what only the app can say, it passes in.
Fakes for apps' tests are in testing.dart.
An instance's basics now name the app it serves (`app`, set by the
host's configuration), and an app accepts only an instance of its own.
SerialQueue and CoalescingRunner move into halkyon_core.
