Active: Number input should have a default number to start. The input should never be empty.

Helper text: Helper text appears below the label when the input is active. Helper text remains visible while the input is focused and disappears after focus away.

Error: Error messages appear below the input field and are always present while invalid.

Disabled: Disabled state should have a .not-allowed cursor on hover.


Number input labels should use sentence case, with only the first word in a phrase and any proper nouns capitalized.
