- Add gear button in header to open account settings modal
- Modal covers Organization, Bank, Account, Logo upload, and Printer Offset fields
- PUT /api/account/:id backend endpoint with full field validation
- Logo file reader with inline preview; only updates logo if a new file is chosen
- CSS for btn-header-icon, settings-section-label, logo-preview, form-row-4
- Add GnuMICR.otf (tracked alongside existing GnuMICR.ttf)
- 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
