/* Course 3 (保育実践研修) application form (step1-3 + confirm) visual redesign.
   Namespaced under .c3app-page so it cannot leak into / collide with any
   other page's CSS, and built as its own component set (not an override
   layer on top of the shared registration_wizard.css .rwiz-* classes or
   the legacy .page-shell/.schedule-table markup) so no !important stacking
   is needed. Structure/tokens follow the approved reference mockup
   (JWSA_Course3_Registration_Form_to_Confirm_Design_Preview.html) 1:1,
   renamed to a c3app- prefix throughout. */
