   CAMPAIGN.SCSS — port nguyên các class giao diện từ prototype đã duyệt 22/09
   (Salemans - Prototype (gui khach).html). Chỉ lấy phần MÀN ĐIỆN THOẠI; đã bỏ
   khung review (sidebar, .stage, .ph, .desk, .tokens) vì đó là công cụ trình bày.
   Ảnh nền + KV nạp qua import TS và gán inline (tránh gotcha url() của Vite+Sass);
   ở đây chỉ giữ background-color mép + lớp scrim. Biến màu lấy từ generated/tokens.
