"""a stored site_name of the old default follows the rename to Inkwell

Revision ID: 0030
Revises: 0029
Create Date: 2026-10-06

The app was renamed from ThoughtSync to Inkwell. The Settings page saves every key,
so most servers have a stored `site_name` of the old default without anyone choosing
it. The row is rewritten only when it holds exactly that; a typed name is left alone.

The match is on the stored JSON text (`settings.value` is `json.dumps(value)`), so
`'"ThoughtSync"'` is the whole of what it looks for.

## Downgrade

Puts the old default back on a row holding exactly the new one. A server where the
admin typed "Inkwell" themselves between the two cannot be told apart from one this
migration rewrote; on downgrade both read "ThoughtSync", which is what the old code
would have shown for either.
