/* ============================================================
   SALESUPPORT — Layout CSS (Sidebar + Topbar + Main)
   ============================================================
   ไฟล์นี้เก็บ "โครงหลัก" ของทุกหน้า — sidebar, topbar, content area

   👤 ใครแก้ได้: แอดมินระบบ
   🎯 แก้ทำไม: เปลี่ยนความกว้าง sidebar, สี, layout behavior

   หลักการ:
   - ทุกค่าใช้ CSS variables จาก tokens.css
   - รองรับ responsive — sidebar ย่อบนมือถือ
   - ไม่มี magic number — ทุกค่ามาจาก token
