   Conventions:
   • All custom classes are prefixed with .bx-
   • Colors come from --bx-* CSS variables (see 01)
   • State suffixes use plain words: .active, .open, [open]
   • Modifier suffixes follow BEM-ish style: .bx-blog-card-sm (compact)
   • Animations: keyframes named bx-* (see section 03)
