 ### Number-to-digits cutoff
 Controls when numbers are read as digits instead of words.
-- **Default:** `2025` (current year)
-- Example: With a cutoff of `2025`, numbers above this are read as digits.
+- **Default:** `2100`
+- Example: With the default cutoff of `2100`, `12345` is read as "1 2 3 4 5" while `1200` is read as "twelve hundred".
 - To spell out larger numbers, set the cutoff higher (e.g., `300000`).
