// Example: seed an account with hand-entered holdings, for institutions whose
// investments Plaid can't fetch (e.g. Ally Invest). Copy, fill in YOUR account id
// (the `accounts.id` Plaid gave it — see the accounts table) and your positions
// from the brokerage's holdings screen, then run: node scripts/<your-copy>.mjs
// Idempotent — re-running upserts. Needs FINANCE_DB_PATH or ./data/finance.db.
// Keep your copy out of git: name it seed-*-holdings.mjs (gitignored) or add it
// to .gitignore yourself — it contains real positions.
