Is it possible to enforce a numbers only input with a numerical minimum on a Text/Numeric price field? I'm guessing it could be done with jQuery, but I would rather have this set up in the Civi Admin UI, since it would be much cleaner.

More details:

I have a price field set up like this:

On the front end, it looks like this: (but I want 4 to be the lowest allowed number, with no letters input)

enter image description here

Basically, I want the HTML equal of <input type="number" min="4"/> in the cleanest and safest way possible. (safe as in not hacking up some jQuery and then moving an element 3 months later and breaking it)

Ideally you would develop a little extension that uses the validateForm hook (check https://docs.civicrm.org/dev/en/latest/hooks/hook_civicrm_validateForm/). This will allow you to refuse input that does not meet your criteria.
