Sometimes I forget like, what the masc/fem variants of a given pet
actually look like? Some are super obvious about things like eyelashes,
and others use more subtle eye differences.
This is a cheap lil hack to make it easier to open a reference! Ideally
I think it would be neat to like, when you hover over an option, have
it show you the reference variant of that pose? But this is good enough
I think!
Most notable change here is extracting the pose option bubbles into a
`data-type="radio-grid"`, and pulling that into the `.support-form`
CSS. My rationale is that, unlike most fields, this field benefits from
being 100%-width, and I don't want to specify that as an override if I
can avoid it, because that's fragile-y.
Instead, I extract this into a generic type of field that
`.support-form` can use (it feels pretty reusable anyway!), and require
the caller to specify how many columns they want as `--num-columns`.
