/*
 * Slider ảnh dự án — reti/project-gallery
 *
 * WordPress chỉ nạp file này khi khối có mặt trên trang (cơ chế của block.json),
 * nên xoá khối là CSS biến mất theo.
 *
 * Dải ảnh là scroll-snap THUẦN CSS: không có JavaScript vẫn vuốt/cuộn được từng
 * ảnh. view.js chỉ thêm mũi tên, thumbnail và phím mũi tên khi đã chạy xong và
 * gắn class `is-ready` — chưa có class đó thì các điều khiển ấy ẩn, không có nút
 * chết nằm trên trang.
 *
 * Màu lấy từ biến của theme, giá trị sau dấu phẩy là lưới an toàn.
 *
 * VỀ ĐỘ TƯƠNG PHẢN: chữ trắng trên cam #ef532d đạt 3,53:1 — đủ cho chữ lớn,
 * chưa đủ cho chữ thường (cần 4,5:1). Nút hành động dùng cam đúng như thiết kế;
 * muốn đạt 4,5:1 thì đặt --reti-pg-action-bg thành #d23606 (brand-hover).
