Yōkai-Y2K v1.9.7.5.9

Additions

• Taste profile under Settings → Library → Recommendations. Pull your library from AniList / MyAnimeList / Kitsu (per-tracker toggles), auto-refresh on a Never / 7 days / 30 days schedule, manual refresh button with a 60 s cooldown, and a last-refresh summary line. Used by the related-mangas carousel to personalize what gets shown
• Candidate injection under Settings → Library → Recommendations (both default on). Tag search on current source runs your top taste-profile tags as searches on the current source. Cross-recommendation from favorites looks your top-rated tracked manga up on the current source and pulls each match's related-mangas list. Silently produce nothing when the taste profile is empty
• Reranking under Settings → Library → Recommendations. Master toggle Rerank by taste (default on) reorders the carousel against your taste profile and drops manga already in your library. Two sliders tune the behavior: Recommendation style (Popular ← → Personalized) controls how much taste weighs vs. the source's own popularity ordering; Serendipity (Familiar ← → Adventurous) reserves exploration slots and boosts rare tags. Both sliders are disabled when Rerank by taste is off
• Filters under Settings → Library → Recommendations (both default on). Hide already-tracked drops Reading / Completed entries from the carousel. Hide dropped drops Dropped entries. Plan-to-read and On-hold entries are now allowed back into the carousel as reminders
• Full-screen "See all" browse for related mangas. A "See all (N)" card appears at the end of the carousel when the pool exceeds 30 candidates; tapping opens a dedicated grid with no cap. Long-press to multi-select; bulk actions include Add to library (single category-set applied to every selection), Select all, and Invert selection. Grid column count scales to screen width, so foldables and tablets get more columns

Changes

• Related-mangas carousel now activates source-native related-mangas data by default on every HTTP-backed extension. Hundreds of installable extensions immediately surface real source data alongside the existing keyword-search fallback and tracker recommendations
• Related-mangas carousel now collapses duplicates across streams. A manga returned by source-native, an AniList recommendation, and a favorite's related list at once now shows as one card instead of three
• Slow tracker recommendation endpoints no longer hang the related-mangas carousel. Each fetch now has a 15 s cap; on timeout the slow tracker is skipped and the carousel finishes populating from the rest
• Bulk-adding many mangas via the "See all" browse no longer freezes the UI for a few hundred ms while the category picker processes the selection

Fixes

• Long-pressing a card in the related-mangas carousel no longer surfaces the chapter-list context menu by mistake
• Multi-selecting sources in Manage Sources and removing them from a group now writes the correct merge state and refreshes the chip row in place without needing to reopen the manga
• After fully un-merging a group and re-merging a subset, members that were left out are no longer silently re-admitted on the next library refresh
• Multi-source groups with members bound to different tracker IDs for the same service no longer silently overwrite one with the other on reconciliation. Ties leave both members untouched; propagation runs only when there's a strict majority

Other

• New per-tracker library cache for the taste profile. Cache is rebuilt on demand from the tracker APIs and isn't included in app backups
• Documentation reorganized: docs/ now holds only user-facing guides; maintainer-only docs moved under docs/dev/. New docs/backup-restore.md covers Y2K ↔ upstream Yōkai backup compatibility and the .yokai → .y2k package-suffix migration
