Major changes: - Textbook UI: chapter list, reader, and interactive exercise view (keyboard + Apple Pencil) surfaced under the Course tab. 30 chapters, 251 exercises. - Stem-change conjugation toggle on Week 4 flashcard decks (E-IE, E-I, O-UE). Uses existing VerbForm + IrregularSpan data to render highlighted present tense conjugations inline. - Deterministic on-device answer grader with partial credit (correct / close for accent-stripped or single-char-typo / wrong). 11 unit tests cover it. - SharedModels: TextbookChapter (local), TextbookExerciseAttempt (cloud- synced), AnswerGrader helpers. Bumped schema. - DataLoader: textbook seeder (version 8) + refresh helpers that preserve LanGo course decks when textbook data is re-seeded. - Local extraction pipeline in Conjuga/Scripts/textbook/ — XHTML chapter parser, answer-key parser, macOS Vision image OCR + PDF page OCR, merger, NSSpellChecker validator, language-aware auto-fixer, and repair pass that re-pairs quarantined vocab rows using bounding-box coordinates. - UI test target (ConjugaUITests) with three tests: end-to-end textbook flow, all-chapters screenshot audit, and stem-change toggle verification. Generated textbook content (textbook_data.json, textbook_vocab.json) and third-party source files are gitignored — re-run Scripts/textbook/run_pipeline.sh locally to regenerate.
