- .ai-specs/PROJECT_CONTEXT.md: new 'Language Model (UI vs. Content)' section
(serviceLang ru->cu, fallback chain, scripture, Bible tab independence,
fonts, calendar authority) + content-policy pointer in Critical Invariants.
- .ai-specs/WORKING_POLICIES.md: new 'Liturgical Content Policies' —
never translate service/Bible texts (sourced only), cu texts verbatim
(no normalisation/latinisation), service assembly follows the Typicon.
- DATA_EN.md/DATA_RUS.md: ru/ holds enriched lives only; services fall back
to cu; cu is the authoritative calendar + service texts.
