/* ============================================================
   브랜드 GEO 블로그 — Public (root) prototype v4 · shared styles
   Design source: 브랜드 가이드라인 + 디자인 시스템 접근성 규칙.
   구조는 v3 public editorial 블로그를 1:1 계승, 표현만 v4 브랜드로 교체.

   원본 브랜드 팔레트:
   · Brand Navy #1D2D63 (주조) — deep #141C3C · semi #36406D ·
     light #817E9A · lighter #D2D4DE
   · Brand Brown #D6A679 (포인트) — deep #B69471 · semi #D8B997 ·
     light #EFD3BE · lighter #FBF7F3
   · Mild Beige #F2F1EA (서브) → 교차 섹션 배경
   · 악센트(보조 안내 전용): blue #3C9DD8 · green #73B670 ·
     orange #DB914C · red #D9613A
   · 브라운 골드 텍스트는 네이비 배경 위에서 사용해 대비를 유지한다.
   · 서체: Pretendard Variable(국문 본문) · Plus Jakarta Sans(라틴 디스플레이)

   이진 radius 규칙: 인라인 버튼/탭 = 사각(0) · 플로팅 = 원형
   섹션 리듬: 80px(mobile) → 120px(≥600px) · 국문 16px/1.7 keep-all
