   KHI Wellness — BỘ NỀN + KHO THÀNH PHẦN  (bản 2, sửa 30/07)
   Hướng: wellness mềm, app-like — NHƯNG:
     · KHÔNG đổ bóng ở bất kỳ đâu (Dang chốt)  → phân tầng bằng NỀN
     · KHÔNG viền ở trạng thái tĩnh — viền CHỈ hiện khi rê chuột (Dang chốt 30/07)
       (giữ border 1px transparent để hover không làm nhảy layout)
     · Bo góc nhẹ vừa, không bo tròn kiểu viên thuốc
     · Trang phải ĐỘNG — tinh thần KHI là chuyển động
