Build 378 is on TestFlight

[briarrrn]

Build 378 is on TestFlight. Two new things I'd most like you to try.

Please test

• Covers for books without art. Books with no cover now get a generated one instead of a grey box. Tell me if any look wrong or are hard to read.
• The setup after sign-in. Add a profile, or sign in fresh, and a short setup lets you pick which kinds of books and libraries to show, and turn on Fanfic Updates or Read & Listen preparation. Every step can be skipped.

Also in this build

• On iPad, the reader stays open when you open it from Book Detail, the Stats month list or a request, so Contents and Settings no longer close by themselves.
• Themed pages (sepia, dark) no longer cut off the tops of lines.
• Each Library shelf keeps its own sort.
• Series with slightly different names, like "X" and "X Series", now stack together.
• Peek lets you highlight and add notes without moving your place.
• Widget covers can stay in full colour on a tinted or clear Home Screen: long-press the widget, Edit Widget, Cover Colour.
• Jump Ahead in the player works on a device that doesn't have the ebook downloaded.
• Read & Listen finds its place in books with long front matter.

Good to know
Passkeys and full SSO sign-in aren't open to third-party apps like Apogee on BookOrbit yet. SSO works through your server's sign-in page with most self-hosted providers, but not with passkeys, Google or Microsoft. More in #164.

The full list is in Settings, What's New. If something's off, More, Feedback & Bug Reports, Report a Problem sends me what I need.
