/*
  TRACKWEAR VISUAL SYSTEM
  -----------------------
  The layout deliberately avoids a centered, template-like e-commerce grid.
  Product cards use a staggered "stream" so the catalog feels like inventory in circulation.
  Thai font safety: no external font dependency. The stack prioritizes Thai-capable system fonts
  and falls back to common UI fonts if Noto/Leelawadee is unavailable.
