/**
 * Enrollment island styles (P2).
 *
 * Front-end styling for the class-registration enrollment island rendered into
 * #class-reg-enroll-root. Every selector is scoped under that root so the island
 * never leaks styles into the surrounding theme (and the theme's resets do not
 * clobber the island's own controls). Light theme only, to match the site's
 * white-card look.
 *
 * Class vocabulary (kept in sync with enroll.js / the island template):
 *   .clsreg-layout            two-column grid: .clsreg-main + .clsreg-cart
 *   .clsreg-players           student selector + add-player card
 *     .clsreg-student           one selectable student chip (label > checkbox)
 *     .clsreg-add-player        the "new player" sub-form
 *   .clsreg-programs          responsive grid of program cards
 *     .clsreg-program-card      one program (name, location chips, sessions)
 *       .clsreg-loc               a location filter chip (.is-selected)
 *       .clsreg-session           a bookable session row (.is-selected/.is-full)
 *         .clsreg-seats             seats-left badge (--low / --full / --open)
 *   .clsreg-cart              sticky side panel -> fixed bottom bar on mobile
 *     .clsreg-checkout          the red pill checkout button
 *
 * @package ClassRegistration
