/* ==========================================================================
   잡토이(JOBTOY) UI 디자인 시스템 — littleBits Inspired STEAM & Maker Edition
   - 레퍼런스: https://littlebits.com/ (Sphero littleBits STEAM Design System)
   - 핵심 디자인 철학:
     1. Clean Studio Canvas: 인공적인 파스텔 그라데이션을 배제하고 순백(#FFFFFF)과
        쿨 알라바스터(#F4F6F9), 딥 차콜(#141923)의 명쾌한 대비로 신뢰감과 가독성 확보
     2. littleBits Functional Color Coding:
        - Power Blue (#0072CE) : 브랜드 중심, 네비게이션, 기초/구조
        - Input Magenta (#E01E68) : 핵심 액션(CTA), 강조 포인트, 메이킹
        - Output Green (#00A651) : 하드웨어/피지컬컴퓨팅, 프로젝트 완성
        - Wire Orange (#F57C20) : 단계별 연결, 창의 융합 포인트
        - Logic Purple (#6236B5) : 성인 AI 교육자 & 기업 AX 스페셜 트랙
     3. Generous Whitespace: 섹션·그리드·카드 내부에 충분한 여백 부여
     4. Crisp Minimal Radius: 너무 둥글지 않고 뾰족해 보이지 않을 정도의 정제된 모서리 (4px ~ 6px)
