The character pointing at the fandom had no image associations, so it was
itself unused and inflated the dry-run count to 2. Tag it on a real image so
it is used (the real-world shape) — the fandom survives via a live character.

The fandom/chapter exclusions added in fb05c5e only touched find_unused_tags
(the preview SAMPLE). prune_unused_tags re-implemented the predicate inline for
the dry-run COUNT and the live DELETE with only the image_tag + series_page
checks — so the preview showed a safe list of names while the delete removed
every fandom (and chaptered series). Operator-flagged 2026-06-08: real data loss
— assigned fandoms deleted, their characters SET-NULLed.
Extract _unused_tag_conditions() as the single source of truth and use it for
the preview, the count, AND the delete, so they can never diverge again. Added a
prune-commit test asserting the LIVE delete spares a character's fandom and a
chaptered series.

find_unused_tags only excluded tags with image_tag or series_page references, so
it flagged every fandom as 'unused' — fandoms are NEVER applied to images (a
character carries its fandom via tag.fandom_id), and the FK is ondelete=SET NULL,
so deleting one silently strips the fandom off all its characters
(operator-flagged 2026-06-08: artist-OC fandoms showing as unused).
Exclude tags referenced as a character's fandom_id, and (same class of gap) tags
referenced by a series_chapter (an all-placeholder series has chapters but no
pages yet). A genuinely orphaned fandom with no characters is still swept.

Adds an ordered chapter layer to series. Reading order becomes
(series_chapter.chapter_number, series_page.page_number); a chapter may be a
placeholder reserving a slot, and carries an optional parsed stated-page range
used to flag missing-page gaps. An image still lives in at most one series ⇒ one
chapter (image_id stays UNIQUE).
- models: series_chapter; series_page gains chapter_id (NOT NULL, cascade) +
stated_page. Migration 0040 backfills every existing series into one
auto-chapter holding its current flat pages — no data loss.
- SeriesService: chapter CRUD (create/update/reorder/delete/merge), page→chapter
assignment, reorder_pages, chapter-aware set_cover; list_pages now returns
chapters[] + gaps[] alongside a back-compat flat pages[]. Legacy series-wide
reorder operates on the single default chapter and rejects multi-chapter series.
- API: chapter endpoints under /api/series/<tag>/chapters; POST pages accepts an
optional chapter_id.
- TagService.merge now repoints series_chapter too, so a merged series' chapters
(and their pages) survive the source tag's deletion instead of cascading away.
- Tests: new chapter suite; updated the 4 direct SeriesPage(...) constructions to
supply chapter_id.
Frontend (chapter-aware manage view + reader) lands next; until then the
existing UI keeps working via the flat pages[] + single default chapter.

Wipe every general + character tag so the operator can re-tag from scratch via
the Camie auto-suggest, while PRESERVING fandoms, series (+ series_page order),
and each image's stored tagger_predictions (so suggestions repopulate
immediately). One set-based DELETE FROM tag WHERE kind IN ('general','character')
— the five tag-referencing tables all cascade, so applications + aliases +
allowlist + rejections + centroids clear automatically; series tags aren't
deleted so series survive; Tag.fandom_id is SET NULL so fandoms are untouched.
Reuses the established dry-run-preview -> confirm pattern: cleanup_service.
reset_content_tagging() + POST /api/admin/tags/reset-content +
TagMaintenanceCard section with a backup-first warning and a red confirm
showing exact counts (tags by kind + image applications). Irreversible except
via DB backup restore; the wipe only fires when the operator confirms.
Tests: service dry-run counts + live delete preserves fandom/series/series_page
while content tags + their image_tag cascade away; API dry-run wiring.
