Three things, and the third one I first said was impossible.
Nový účet takes the full width — a 420px column inside a full-width panel
left two thirds of the row empty. Three across on a desktop, one on a
phone.
Rodinné nastavení edits `onboarding_template`: the shared sources a new
member's first setup pulls down. The values are plaintext credentials — a
prehraj.to login and a TorBox key — so they are masked behind a reveal
toggle, and this stays a superuser-only noindex page. It PATCHes the one
record and never creates a second; a second row would make the hook's
`-updated` ordering silently decide which config the family gets.
"Použít rodinné nastavení" pre-loads that config onto the account being
created, so the new person never types a family code. I claimed this could
not work because `addon_config` is keyed by profile and a fresh account has
none. The owner pushed back, correctly: the old wizard needed a profile for
the same reason and simply could not make one, whereas this page can — and
`CloudSyncService._findOrCreateDefaultProfile` looks for an existing
profile BEFORE creating one, explicitly "so a second device signing into an
account with data doesn't make a duplicate". A profile made here is adopted
as the default on first sign-in. The other two obstacles were never real:
the template is superuser-readable, and the password is available because
this page just chose it.
The crypto is lifted unchanged from index.html and verified rather than
trusted: the page's own functions, run against
amber-app/test/_fixtures/pbkdf2_vector.json — the same fixture
addon_config_crypto_interop_test pins the Dart side to — derive the
identical key, and a sealed blob round-trips. One wrong iteration count
would have made a new member's app fail to decrypt, which presents as a
password reset rather than as a bug.
The account is created BEFORE the pre-load, and a failed pre-load says so
in warning colour rather than reporting success or rolling back: a
half-made account you were not told about is the worst outcome of the
three.
