Character Counter Input Group (Textarea) for Ark UI

A message textarea with a fixed 0/500 in a footer row, and typing stops at 500 characters.

A message box has a footer under the text, with a line between them. The footer shows 0/500 at its end. The count does not change while someone types. The textarea stops at 500 characters.

Use it for a comment that must stay under 500 characters. A single-line cap fits an Input better. In React, Ark UI does not recount 0/500 while someone types.
