/* ========================================
   nbuntu 테마 — Terminal-Inspired Light

   "sudo rm -rf doubt && ./ship-it"

   터미널 감성은 유지하되, 라이트 테마로 읽기 좋게.
   Velocity(Obsidian) 스타일 참고.

   커스터마이징:
   - 변수 값을 바꾸면 전체 스타일이 바뀜
   - icons/ 폴더에 아이콘 넣으면 콜아웃 아이콘 교체됨
     (파일명: info.png, tip.png, warning.png, question.png)
