/* ========================================
   CLOUDMOON VPS - ORDER PAGE STYLES (slim)
   Sau khi refactor sang cm-* Tier 2 (components.css):
   - cm-order-layout, cm-order-main, cm-order-sidebar
   - cm-spec-grid, cm-billing-grid, cm-os-grid
   - cm-summary-row/divider/total, cm-order-actions
   - cm-section-title, cm-card
   File này chỉ giữ phần ĐẶC THÙ VPS order page:
   - vps-info-card (header card lớn show thông tin gói + flag + badge)
   - resource spinner (CPU/RAM/Disk addon)
   - coupon section, info-notice (dùng dynamically khi cần)
