Add a Share Book feature that generates an expiring HTTPS share URL plus a
parallel readest://share/{token} deep link. Recipients land on /s/{token},
where logged-in users can one-tap "Add to my library" (R2 server-side
byte-copy) and anonymous users download the book or open it in the app.
Sharers manage active links from a dedicated "Manage Shared Links" panel
under user settings.
Highlights:
- 9 new App Router endpoints under /api/share (create, [token], cover,
og.png, download, download/confirm, import, revoke, list).
- /s landing page with branded next/og chat unfurl image and SSR auth-cookie
detection so logged-in recipients see "Add to my library" as the primary
action without layout shift.
- Server-side R2 byte-copy for /import preserves the project's existing
invariant that every files.file_key is prefixed with its row's user_id;
stats / purge / delete / download routes work unchanged. URL-encodes the
copy source so titles with spaces or '&' don't break the copy.
- Universal 7-day expiry cap, no tier differentiation, no "never". DMCA-risk
reduction. Picker defaults to 3 days.
- Position-aware shares: "Share current page" toggle (off by default for
privacy) attaches the sharer's CFI; recipient lands at the same paragraph.
- Per-user 50-share cap, rate limiting via Cache-Control: no-store on
token-bearing responses, atomic SQL increment for download_count via a
SECURITY DEFINER function so the public confirm beacon stays safe under
concurrent fire.
- Soft revocation: presigned download URLs (5-min TTL) cannot be cancelled
before TTL; documented as accepted v1 behavior.
- token + token_hash hybrid storage: public endpoints look up by hash and
never select the raw token, so accidental SELECT-* leakage on a public
route can't expose the bearer credential.
- Mobile / desktop Tauri share via tauri-plugin-sharekit; web falls back to
navigator.share with a clipboard fallback when no native share method
exists. Share-sheet dismissal no longer silently copies.
UI:
- New Dialog with a settings-card group: iOS-style segmented duration picker
+ toggle slider for "Share current page", on a single row each.
- Reader top-bar Share button, library context-menu Share entry, manage-
shares list with cover thumbnails and overflow menu.
- New <SegmentedControl> primitive in src/components for reuse.
Coverage:
- Unit tests for token utils + URL parser (20 new tests, full suite at 3445).
- 31 locales translated for all new strings; en plurals hand-added per the
project's hand-curated en convention.
DB migration in docker/volumes/db/migrations/002_add_book_shares.sql adds
the book_shares table, RLS policies, and the increment_book_share_download
RPC. Migration is idempotent.

Paginate Supabase select queries in the storage stats API to avoid
the 1000 row default limit. Align StorageManager's formatFileSize
with useQuotaStats calculation so quota values display consistently.

When LANG=C.UTF-8, navigator.language can return 'C' which is not a
valid BCP 47 tag, causing Intl.NumberFormat and toLocaleString to throw.
Normalize POSIX values (C, C.UTF-8, POSIX) to 'en-US' at the source.
