"""Integration tests for the Accordance Port REST API.

Tests all 25 endpoints across 8 endpoint groups using FastAPI's TestClient.
Covers basic 200 responses, Catholic-specific variants, error cases, and
response shape validation.

Endpoint groups tested:
  - Bible (4): list, single verse, verse range, interlinear
  - Lexicon (4): list, lookup, search, metadata
  - Commentary (4): list, section, books, sections
  - Search (2): FTS5 search, transliterated search
  - Canon/Lectionary (4): resolve, parse, books, lectionary
  - Meta (3): modules, health, index status
  - Acc2 (3): list, paragraphs, paragraph by number
  - Morphology (1): word morphology by verse
