/* ===================================================================
   TOP EDU PREP — 2026 redesign
   Concept: "일정을 먼저 그린다" — the multi-year exam calendar as the
   brand's visual signature. Ultramarine field, cool paper, saffron bars.
   Flat planes and one animated roadmap instead of hairline-ruled pages.
