/* QCS Form — frontend styles.
 *
 * Design goals:
 *   1. Look polished out-of-the-box on any WordPress theme (light or dark).
 *   2. Stay self-scoped — every selector is prefixed with .qcs-form so we don't
 *      bleed into host-theme typography or accidentally inherit unwanted styles.
 *   3. Theme-able via CSS custom properties — site owners override --qcs-* vars
 *      from their child theme without forking this file.
 *
 * Override examples (drop into theme stylesheet):
 *   .qcs-form { --qcs-brand: #16a34a; --qcs-radius: 12px; }
 *   body.dark-theme .qcs-form { --qcs-bg-field: #1f2937; --qcs-text: #f9fafb; }
