  COMPONENTS — các khối UI dùng lại ở từ 2 module trở lên (card, badge, button, form, row...).
  Đây là "thư viện component" nhắc tới ở CLAUDE.md mục 2 (/shared-ui).
  QUY TẮC: một class ở đây phải được ít nhất 2 module dùng. Nếu chỉ 1 module dùng, chuyển
  xuống css/modules/<module>.css — xem .claude/skills/design-system/SKILL.md mục 4.
