/* assets/css/components/feedback-form.css
 * @layer components — Customer Feedback Form
 *
 * Layered on top of:
 *   - form.css       (form-group, .form-group__field, error states)
 *   - contact-form.css (shell, status alert, contact-form__row, submit button)
 *
 * Owns only the feedback-specific atoms:
 *   - .feedback-form         shell (extends contact-form shell)
 *   - .feedback-form__preamble warm cream "Dear Customer" panel
 *   - .fb-section            numbered eyebrow + hairline rule
 *   - .fb-score              segmented 1-5 slider with tooltip
 *   - .fb-yn                 paired Yes/No capsule
 *   - .feedback-form__footer privacy line + submit button row
 *   - .feedback-form__thanks success panel
 *
 * All values flow through tokens — no hardcoded hex / px / rem.
