/* =====================================================================
   base.css — ฐานของทั้งระบบ (หน้าเว็บ + หลังบ้าน + แลนดิ้ง)
   =====================================================================

   กติกาของไฟล์นี้ (สำคัญ — ทำผิดแล้วจะกลับไปพังแบบเดิม)

   1. "หนึ่งคลาส ประกาศที่เดียว"  ห้ามมีไฟล์อื่นมาเขียนทับคุณสมบัติเดิม
      ของ .btn / .card / .form-control ฯลฯ อีก — ถ้าอยากได้หน้าตาต่าง
      ให้เพิ่ม modifier ใหม่ (เช่น .btn--xxx) แทนการ override

   2. ห้าม hardcode สี  ใช้ var(--c-*) หรือ var(--gold*) / var(--lux-*)
      ที่ปั้นจากธีมเท่านั้น (ยกเว้น #fff/#000 ที่เป็นคู่ผสมของ color-mix
      กับสีเหรียญเงิน-ทองแดง ที่เป็นสีเชิงความหมาย)

   3. ห้ามใส่ z-index หรือ transform ให้ container ของเนื้อหา (.page/.container)
      เพราะจะสร้าง stacking context แล้วกด modal/sheet ที่อยู่ข้างในจนคลิกไม่ได้

   ลำดับโหลด:  theme.css → base.css → utils.css → app.css | admin.css | landing.css
