/* ============================================================
   QUEENDOM LED — /catalog/ Stylesheet (VI-Compliant v1.0)
   Base: online style.css?v=20260930a (deployed variant, 875 lines)
   VI rules (国际部对外VI系统 V1.0): red #C00820 is NEVER used as
   text color; red appears only as 3px lines / small dots / accent
   bars. Silver-chrome gradient + ink text on all CTA buttons.
   Changes vs base: text colors + 3px red accent lines + button ink
   text with inset red line. Layout / spacing / grid untouched.
