Create a beginner-friendly accessible feedback form with a semantic section, labelled heading, fieldset and legend for a required radio rating, an optional labelled textarea, and a submit button. Keep every custom selector under .cf-feedback and ensure every selector is represented in the supplied HTML so live CSS edits visibly update the preview. Use real form controls, visible keyboard focus, readable contrast, 44px touch targets, responsive stacking from 320px, and reduced-motion handling. Keep radio labels clickable and never hide the focus state. Do not use JavaScript, external assets, framework classes, or unlabeled controls. Return complete copy-ready HTML and dependency-free CSS, then explain the fieldset and responsive decisions.
