/**
 * GCC Typography — Mobile Modal  v2.3.0
 *
 * Bỏ FAB. Chọn vùng → modal hiện luôn.
 *
 * v2.3.0 — Migrated to GCC Design Tokens system.
 *   • Tất cả màu sắc → var(--gcc-*) tokens.
 *   • Phụ thuộc gcc-tokens.css load TRƯỚC (qua wp_enqueue dependency).
 *   • Đổi tone toàn site = sửa gcc-tokens.css, không động đến file này.
