## Bible — Human-Readable Pages (HTML)

The site serves interlinear Bible pages showing two translations side by side.
These are the canonical URLs for citing or linking to Bible passages.

### Interlinear Slugs
- latin-bibel = Latin + German (Clementine Vulgate + Menge)
- latin-bible = Latin + English (Clementine Vulgate + Douay-Rheims)

Single-language slugs (/bible/, /bibel/, /latin/) redirect 301 to their
interlinear counterpart. Always use the interlinear slug for stable links.

### HTML URL Patterns
- Book landing:  /{slug}/{book}/
- Chapter:       /{slug}/{book}/{chapter}/
- Verse:         /{slug}/{book}/{chapter}:{verse}/
- Verse range:   /{slug}/{book}/{chapter}:{from}-{to}/

IMPORTANT: Verse references use a COLON between chapter and verse number,
not a slash. /ephesians/6:11/ is correct; /ephesians/6/11/ is NOT a valid
HTML page URL (it is a JSON API pattern only).

### Book Name Localisation
HTML URL book slugs follow the first language in the combo:
- /latin-bibel/{book}/ → German book names (prediger, psalmen, matthaus, etc.)
- /latin-bible/{book}/ → English book names (ecclesiastes, psalms, matthew, etc.)
Cross-language names also resolve (the router tries all datasets), so
/latin-bibel/ecclesiastes/ and /latin-bibel/prediger/ both return the same page.

### HTML Examples (all return HTTP 200)
- Ephesians ch. 6 (Latin+German):       https://latinprayer.org/latin-bibel/ephesians/6/
- Ephesians 6:11 highlighted:           https://latinprayer.org/latin-bibel/ephesians/6:11/
- Ephesians 6:10-18 range highlighted:  https://latinprayer.org/latin-bibel/ephesians/6:10-18/
- John 3:16 (Latin+English):            https://latinprayer.org/latin-bible/john/3:16/
- Psalm 23 (Latin+German):              https://latinprayer.org/latin-bibel/psalmen/23/
- Genesis 1 (Latin+English):            https://latinprayer.org/latin-bible/genesis/1/
- Prediger / Ecclesiastes ch. 1:        https://latinprayer.org/latin-bibel/prediger/1/

index, translation index), and cross-references to the same passage in the
other two translations. Each verse includes a citation field formatted for
proper attribution (e.g., "Genesis 1:1 (Douay-Rheims)").

Single-verse responses include top-level "verse", "text", and "citation"
fields for convenience, plus navigation to previous/next verse.
