/**
 * Hilanaw Sponsorship — Redemption Page
 * @package Hilanaw_Sponsorship
 * @version 1.0.0
 *
 * Reuses the exact same design tokens as sponsor-auth.css (which itself
 * mirrors chat-ui's [hilanaw_auth] page) so the entrepreneur-facing
 * redemption page feels consistent with both the sponsor pages and the
 * main platform.
