Die max()-Semantik aus v14 verglich nur die grobe scroll_fraction. Da
scroll_fraction und position_anchor gemeinsam, aber entkoppelt gespeichert
werden, konnte ein einzelner Save mit transient zu hoher fraction (z.B.
instabiles Layout beim Laden) die Position dauerhaft einfrieren: jeder
spätere echte Fortschritt hatte eine kleinere fraction und wurde inklusive
Anker verworfen — der Leser landete immer wieder an derselben Stelle.
Fix: Vergleich läuft jetzt über den Blockindex im Anker (die Größe, die
auch die Sprungposition bestimmt), mit innerFraction als Tiebreaker.
scroll_fraction dient nur noch als Fallback für PDFs ohne Anker. Server
(_progress_is_further) und Client (_cmpProgress) nutzen identische Logik;
loadBookList-Push und lokaler Cache ebenfalls. Bestehende eingefrorene
Einträge entfrieren sich beim ersten Weiterlesen selbst.

Der am weitesten gelesene Wert hat immer Vorrang:
- Server: scroll_fraction = max(neu, aktuell) — ein afk-Fenster bei 10%
kann nicht mehr 80% überschreiben
- Client loadBookList: wenn lokaler Fortschritt > Server, wird gepusht
und für die Anzeige verwendet (deckt Offline-Lesen ab)
- Pending-Flag-Logik entfernt — nicht mehr nötig dank max-Semantik
- saveReaderProgress(force=true): neuer force-Parameter schreibt
Position unabhängig vom gespeicherten Maximum; Button ⚑ im
Reader-Header für den Ausnahmefall "zurück-zum-Anfang"

Timestamp-Vergleich in _saveBookMeta entfernt: client-seitige
ISO-Strings (new Date().toISOString) lagen fast immer leicht vor dem
Serverwert und haben dadurch regelmässig korrekten Online-Fortschritt
überschrieben.
Neu: explizites Pending-Flag (localStorage diora_pending_progress) —
gesetzt wenn saveReaderProgress offline scheitert, gelöscht nach
erfolgreicher Synchronisierung.
- _saveBookMeta nutzt das Flag statt Zeitstempel: Server-Daten
überschreiben lokalen Fortschritt nur wenn kein Pending-Flag gesetzt
- _syncPendingProgress: pusht ausstehenden Fortschritt beim
online-Event bevor loadBookList läuft
- saveReaderProgress setzt das Flag nur wenn !navigator.onLine

- _saveBookMeta vergleicht local vs. Server last_read — neuere lokale
Daten (offline gelesen) überleben den nächsten Server-Abruf
- loadBookList pusht beim Online-Werden automatisch lokal neueren
Fortschritt an den Server bevor die Liste gerendert wird
- saveBookmarks/saveHighlights markieren fehlgeschlagene Saves als
pending sync (localStorage); beim nächsten online-Event werden alle
pending Annotationen zuerst gepusht, dann erst die Buchliste geladen

Statt padding-top gegen die Navbar zu kämpfen ist #tabs jetzt
position:fixed direkt unterhalb der Navbar (top:var(--nav-h),
z-index:150). Damit ist die Leiste garantiert immer sichtbar,
unabhängig vom Scroll-Zustand oder Offline-Status.
main-content padding-top auf calc(var(--nav-h)+3rem) erhöht um
Platz für Navbar+Tabs zu schaffen. Offline-Banner vereinfacht zu
einer body-Klasse (kein fixed DOM-Element mehr).

- main-content padding-top auf calc(var(--nav-h) + 0.75rem) erhöht
damit die Tab-Leiste (Radio/Focus/Podcasts/Books) sicher unterhalb
der fixed Navbar liegt — auf Desktop und Mobile
- SW v10: sendet SW_ACTIVATED an alle offenen Tabs wenn ein neuer SW
übernimmt; app.js lädt daraufhin neu (außer wenn ein Buch geöffnet
ist) — verhindert dass der Browser eine uralte HTTP-gecachte Version
ausliefert

- Bei Offline-Start oder Wechsel in Flugzeugmodus: roter Banner
unterhalb der Navbar, automatischer Wechsel zum Books-Tab (einziger
sinnvoller Tab offline), Upload-Zone wird ausgeblendet
- Bei Rückkehr online: Banner verschwindet, Upload-Zone erscheint wieder,
Buchliste wird neu synchronisiert
- openBook unterscheidet jetzt zwischen "nicht gecacht" (Toast-Hinweis
zum einmaligen Online-Öffnen) und echtem Defekt (markBookBroken wie
bisher) — kein stilles Scheitern mehr
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Ohne diesen Fix schlägt das Öffnen der App im Flugzeug fehl, weil der
Service Worker die HTML-Seite (/) nicht cached — der Browser zeigt
dann eine Netzwerkfehler-Seite bevor JS überhaupt startet.
Strategie: Network-first für Navigationsanfragen, bei Netzwerkfehler
die zuletzt gecachte Version ausliefern. Nach dem ersten Online-Besuch
funktioniert die App vollständig offline.

Ohne navigator.storage.persist() ist der IndexedDB-Speicher "best-effort"

Chrome 98+ hat Probleme mit kombinierten purpose-Werten ("any maskable")

- IndexedDB v2 mit zwei neuen Stores: book_meta (Buchliste +
Lesefortschritt) und book_annotations (Lesezeichen & Highlights)
- loadBookList fällt bei Netzwerkfehler auf lokalen Meta-Cache zurück,
blendet Upload-Zone aus und zeigt Offline-Hinweis
- Leseposition (scroll_fraction + position_anchor) wird bei jedem
Auto-Save lokal gecacht, sodass offline-Öffnen am richtigen Ort
landet
- Lesezeichen und Highlights werden nach Server-Abruf lokal gecacht
und bei Netzwerkfehler von dort geladen; Änderungen offline bleiben
bis zur nächsten Synchronisierung erhalten
- Mobile Reader-Header: kompaktere Abstände, Fortschritts-Input auf
kleinen Screens ausgeblendet

replace-data endpoint now optionally accepts meta_ct/meta_iv.
The client extracts title/author from the uploaded file (same as
normal upload), re-encrypts metadata with the current key, and sends
both data and meta together — so broken books are fully restored
including their displayed title and author.

When a book fails to open, a '!' button appears next to it in the list.
Clicking it prompts for the original file; the file is re-encrypted with
the current key and replaces the broken ciphertext on the server while
keeping all metadata, progress, highlights and bookmarks intact.
- Add POST /books/<pk>/replace-data/ endpoint (updates data only)
- Add _evictCachedBook() to clear IndexedDB cache for a single book
- Replace complex client-side re-encryption on password change with a
simple confirm() warning that books will need to be re-uploaded

The old key comparison was wrong — the localStorage key may have been
randomly generated rather than PBKDF2-derived. Fix:
- Add /accounts/check-password/ to validate the old password server-side
before touching any keys
- Use the localStorage key directly as the old decryption key (it is
always the correct source of truth, regardless of how it was generated)
- Derive the new key from the new password via PBKDF2
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The encryption key is PBKDF2-derived from the login password. Changing
the password without migrating the key would make all books undecryptable
on the next login.
- Add POST /books/<pk>/rekey/ endpoint to replace a book's ciphertexts
- Password change form is now JS-driven: before submitting to the server,
derives the old key, verifies it matches localStorage, derives the new
key, re-encrypts all books (data + meta) and their highlights/bookmarks,
updates localStorage, then submits the Django form
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Uses Django's built-in PasswordChangeForm and update_session_auth_hash
so the session stays valid after the change. Form is hidden in a
<details> element and opens automatically on validation errors.

renderPdf now takes an optional pivotPage. Pass 1 builds the full DOM
and sizes all canvases (instant). Then scrolls to the pivot page
immediately so the user stays in place. Pass 2 renders pixels from
pivot→end, then pivot-1→start.
reRenderPdf detects the current visible page before re-rendering and
passes it as pivot, so zoom no longer resets scroll position.

Scroll position was restored before browser finished layout, so
scrollHeight was still wrong. Now waits two animation frames after

html/body no longer scroll — overflow: hidden on both.
.main-content gets height: calc(100% - nav-h) and overflow-y: auto

Zoom is now baked into the canvas render scale instead of being applied
via CSS zoom. CSS zoom only scales pixels already on the canvas, causing
blurriness at high DPR (e.g. PWA on mobile). Now the canvas is rendered
at the correct resolution for the chosen zoom level.
Also: stop nulling currentPdfDoc on re-render so PDF.js page cache is
preserved, making zoom re-renders significantly faster.

The 📻 button now opens a sidebar with the currently playing station/track,

Each book gets its own key (diora_reader_settings_{bookId}).
Opening a book resets to defaults then applies book-specific overrides,
so zoom, spread, invert, theme etc. are remembered independently per book.

Spread mode: new toggle in reader settings renders pages side-by-side
(cover alone, then pairs 2-3, 4-5...) using full screen width. Each
page scales to half the container. Navigation and scroll position
tracking are unchanged since per-page IDs are preserved.
Pinch-to-zoom: captures 2-finger pinch on the PDF reader, blocking
native browser zoom. Live CSS zoom during gesture, snaps to nearest
10% step on release. Single-finger scroll unaffected. applyPdfZoom
moved to module level so touch handlers can call it. Touch listeners
cleaned up on reader close.
