Scanned books are commonly distributed as DjVu, which the scanner only stored as a supplement.
Decode pages on the server with DjVuLibre so DjVu imports with a cover and page count, opens in
the image reader with its embedded OCR text, and can be the preferred format of an ordinary email
recipient. Migration 0113 widens the recipient format check to allow it.
Decoding runs on validated private snapshots behind a bounded, reader-first queue, and
revalidation and cached pages are answered without a decoder. Released iOS builds cannot open
DjVu, so series continuation offers it only to callers sending includeDjvu=true, and the
dashboard and notebook read file never name it. The first full scan after upgrading promotes
stored .djvu supplements to content.
Fold six tabs into Recipients, Mail servers, Templates and History, where only problems get
colour and one star sets each default through email_preferences. Replace the send dialog with
a sheet that preselects the default recipient and follows the send. Server additions are
optional fields and routes, so released iOS builds keep working.
Keep one cover slot per medium and show the one each surface needs: the
library's shape for the face, square art on audio screens, the ebook slot
for Kobo and OPDS. Legacy covers convert on upgrade or on first read, and a
write that names no slot keeps working for released iOS builds. Also read
the dev client origin from one constant.
Extract dominant color from book covers to apply ambient background tinting in BookDetailView, add cover tinting toggle to display settings, and test cover tint extraction.
