/* ============================================================
   OLLIN · BUSINESS TOOL THEME
   For daily-use staff app: dense, stable, fast, no decoration.
   Brand colors extracted from https://ollincafe.vn/
   ============================================================
   Philosophy:
     - 1 font (Raleway) for everything. Playfair chỉ cho "Giỏ QR" logo.
     - Radius nhỏ: 4/6/8. Không có 16/20/24.
     - Shadow tối thiểu. Panel dùng border, không shadow.
     - Accent orange = primary action + active state. Không decor.
     - Mật độ cao: row 36-44px, padding 8-12px.
