   탑에듀프렙 — Design tokens
   Signature: the "응시표(admission-ticket)" motif — every exam (SAT/AP/IB/수능)
   hands the student a paper ticket on test day. Cards, CTAs, and exam-date
   entries throughout the site are built as ticket stubs: perforated edge,
   corner stamp, monospace serial/date — because a test-prep academy's whole
   world revolves around that one paper artifact.
