- Schema: account_id FK on checks and layout_fields; UNIQUE per-account on check_no and field_name
- DB: runtime migration recreates both tables to add account_id (assigns existing rows to account 1)
- Routes: GET /api/accounts lists all; GET /api/account/:id replaces hardcoded id=1; POST /api/account/setup always creates a new account and returns accountId
- checks.js: all queries scoped by account_id; POST requires account_id in body
- pdf.js: resolves account from check's account_id instead of id=1; layout fields fetched per-account
- import-mdb.js: always INSERTs a new account (never deletes existing); all records tagged with new accountId
- Frontend: account switcher in header; activeAccountId persisted to localStorage; all API calls pass account_id; switching accounts reloads checks; wizard and import auto-switch to newly created account
- Hardcode GnuMICR.otf path in pdfService.js; remove MICR_FONT_PATH env var
- Fix normalizeDate to handle MM/DD/YY (2-digit year) and return null on no match
- Fix generatePdf button DOM bug: update span directly instead of overwriting textContent
- Remove .env.example and NTFY_URL from docker-compose (app has no required config)
- Remove redundant fonts volume mount from docker-compose (fonts bundled in image)
- Mark MVP TODO items complete; add // TODO comments in source for post-MVP features
- Update README: correct slot height, remove stale env var docs
