Mobile Reading and Transfer UI Fixes
Fixes mobile article back-to-top touch handling, aligns Resource cards, and adapts Quick Transfer to narrow, short, and keyboard-constrained screens without changing security, quotas, or APIs.
# Mobile Reading and Transfer UI Fixes
This release improves mobile reading and the Resources transfer experience without changing backend capabilities or the permission model.
## Knowledge articles
- The Back to Top control is no longer blocked by the fixed Appbar touch layer while reading an article on mobile, so it returns to the article start as expected.
- Real Appbar controls such as Back and Copy remain interactive.
## Resources and Quick Transfer
- The Quick Transfer and Japanese learning cards now share a consistent grid width and card rhythm, with aligned headings, metadata, descriptions, and actions.
- Entry, room, message, upload task, file preview, and composer layouts now adapt to narrow portrait screens, short screens, and mobile landscape; focused inputs remain visible when the software keyboard opens.
- Sign-in remains reachable from a non-Home mobile App, and key controls retain practical touch sizes without clipping content to hide layout problems.
## Unchanged boundaries
This release changes only public interaction and responsive UI. Passphrase derivation, HttpOnly sessions, private R2 storage, 24-hour expiry, standard-account quotas, admin Multipart permissions, download authorization, and existing APIs are unchanged.
