Radio input: poor styling and incorrect behavior across themes

[jerrythomas]

Problem

The radio input type in the themes comparison page (/playground/themes/inputs) does not appear to be styled correctly across themes, and may not function properly (selection behavior).

Steps to reproduce

1. Navigate to /playground/themes/inputs
2. Observe the Radio A / Radio B inputs in the Checkbox & Radio section

Expected

• Radio buttons should match the theme's visual style
• Selecting Radio A should deselect Radio B and vice versa (they share the same name attribute)

Affected themes

All 10 themes — no theme appears to style radio inputs distinctively.

Notes

The InputField radio type may be missing theme-level CSS rules for [type='radio'] elements, or the name attribute grouping may not be wired correctly.

Fixed in 5ef347025939fb184a054c8a924d6d76980f5add — added appearance:none radio styling with primary-colored checked state in base/input.css; fixed InputField usage on comparison page to pass options array.
