/* ============================================================
   Pricing card DÙNG CHUNG (component <x-pricing-card>).
   Dùng ở /thiet-ke-website (3 gói) và /zalo-mini-app (4 gói).

   - Glass liquid-glass §1 (alpha .58 thường / .72 nổi bật), blur 18px, saturate 160%.
   - COLOR LOCK: accent = var(--site-primary…); đỏ --pc-price CHỈ cho giá & badge -%.
   - Lệch tầng: gói nổi bật nhô cao bằng margin âm (không transform → không đụng reveal).
   - Tự chứa biến, KHÔNG phụ thuộc .wd-page → dùng được ở mọi trang.
