/* AiNex 사이버연수원 — 과정 목록 (hrdedu/educourse/course_list.html), redesigned in design step 3.
   Flat 연수원 look: page head like .yw-ph, category tabs like .yw-sn, text cards with a navy top rule.
   Class names are unchanged (prefix .clx-) so the page markup and logic stay as they were. Tokens only, radius 4/6. */
