Summary

  • Stores grammar content as structured JSON instead of markdown round-trips
  • Properly extracts and renders paradigm tables (declension/conjugation charts)
  • Handles nested tables in DIV, SPAN, and CENTER elements from EIEOL source

Changes

  • Added structured content types (ContentBlock, ParadigmTable, ParadigmRow)
  • Refactored EIEOL parser to extract typed blocks (prose, paradigm, example, note, heading)
  • Created StructuredContentRenderer component for proper table rendering
  • Migration adds structured_content JSONB column

Test plan

  • Visit /grammar/la/33-the-pluperfect-tense-forms-of-the-first-conjuga - paradigm tables render correctly
  • Visit /grammar/la/12-the-passive - tables render with proper styling
  • Verify Old Norse and Gothic grammar pages also render tables

Fixes #228
