"""Magazine projects: layout-aware ingestion, article review, podcast scripts.
|
||
|
||
Magazines live in the same store as Read Aloud documents
|
||
(<CONFIG_DIR>/reader_library/<id>/) and are distinguished by meta.json's
|
||
``kind: "magazine"``, so the existing library listing, cover, progress and
|
||
audio endpoints keep working unchanged. Alongside those, a magazine adds:
|
||
|
||
layout.json every classified block on every page, with bboxes
|
||
articles.json detected articles; nothing is narrated until approved
|
||
pages/NNNN.png rendered pages for the PDF view and OCR
|
||
images/*.png extracted figures
|
||
podcast/<id>.json generated two/three-host scripts
|
||
|
||
Ingestion is a restart-safe background job because an 84-page issue takes
|
||
minutes, and the browser must not have to stay open for it.
