   ----------------------------------------------------------------------------
   บล็อกนี้เพิ่มใหม่ทั้งหมด และเป็น "ตัวคุมหลัก" ของพฤติกรรม responsive
   ต้องอยู่ท้ายไฟล์เสมอ เพราะอาศัยลำดับ cascade ทับกฎ responsive เดิมด้านบน

   โครงสร้าง:
     A. Base            — กฎที่จำเป็นต้องอยู่นอก media query
     B. ≤840px          — แท็บเล็ต: sidebar off-canvas, modal sheet, grid 1 คอลัมน์
     C. ≤700px          — มือถือ: ตาราง→การ์ด, topbar กระชับ, ปุ่มเต็มความกว้าง
     D. ≤480px          — มือถือจอเล็ก
     E. landscape เตี้ย — มือถือแนวนอน
     F. pointer: coarse — touch target ≥44px / input ≥16px (วางท้ายสุดให้ชนะ)
     G. prefers-reduced-motion

   หมายเหตุ: ทุกบล็อกที่อิงความกว้างใช้ `@media screen and (...)` เพื่อไม่ให้
   มีผลตอนสั่งพิมพ์ (กระดาษ A4 = ~794px จะเข้าเงื่อนไข ≤840px โดยไม่ตั้งใจ)
   ทำให้ @media print และ .cert-print / .thermal-receipt ทำงานเหมือนเดิม
