/* tram-vutru.css: trang trạm kiểu vũ trụ (làm lại trang Công cụ, 04/10/2026). Nạp SAU tools.css và vutru.css, chỉ khi TRANG_TONG = "vutru".
   Cách làm: tools.css vốn viết cho nền TỐI, rồi đợt 2 (26/09) khoác bộ SÁNG (khối "LỚP SÁNG"). Ở đây đổi bảng biến sang cam kem trên nền vũ trụ
   và ghi đè lại từng chỗ khoác sáng. Mã JS của từng công cụ dùng tên biến cũ (--accent, --text-primary…) nên GIỮ tên, đổi giá trị.
   GĐ1 làm kỹ cho 4 trạm mẫu (Nhịp thở, Nghỉ một chút, Đồng hồ thiền, Uống nước) và phần khung chung; các trạm còn lại làm ở GĐ2. */
