Variable CHECKBOX_FIELDConst
CHECKBOX_FIELD: "relative mt-0.5 focus-visible:ring-ring dark:focus-visible:ring-ring/50 aria-invalid:focus-visible:ring-destructive dark:aria-invalid:focus-visible:ring-destructive pointer-coarse:before:absolute pointer-coarse:before:-inset-4 pointer-coarse:before:content-['']"
A form's 16px checkbox: on touch the hit area grows to 44px without moving it. Light's focus halo runs at full alpha, as the fields' does; at the primitive's 50% it is 1.8:1 there. An invalid box's does in both themes: the primitive's 20% invalid ring would otherwise hide which one has focus.
