# BUG-001 — Age boundary of 18 is incorrectly rejected

- **Priority:** High
- **Severity:** Major
- **Environment:** Chrome 128, desktop
- **Steps to reproduce:**
  1. Open the registration form
  2. Fill in all fields with valid data
  3. Enter `18` in the "Age" field
  4. Click "Create account"
- **Expected result:** Registration succeeds (the hint under the field states "registration is open from 18 years old")
- **Actual result:** The form shows the error "Age must be between 18 and 99"
- **Notes:** Looks like a classic off-by-one error in the comparison condition (`<=` used instead of `<`)
