/* ═══ design-v5.css — 세 사이트(KEY-FREE·KEY-LINK·TECH BRICK) 공용 디자인 층 (2026-09-20) ═══
   ★정본은 Web_sites/shared/design-v5.css 하나. 각 사이트 폴더의 design-v5.css 는 shared/apply_design_v5.py 가 찍어 낸 사본이다 — 직접 고치지 말 것.
   ★모양만 바꾼다. 문구·구조·첫 화면(히어로) 그림과 배치는 건드리지 않는다(9/19 Codex 가 맞춘 값 그대로).
   체계: 종이색 #F4F1EA · 남색 #151B23 · 각진 모서리 · 굵은 윗선 3px + 가는 선 · 큰 문장 제목 + 두 단.
   ☠이 파일은 각 페이지 </head> 바로 앞(페이지 안 <style> 뒤)에 걸린다 — 앞선 규칙들이 !important 를 많이 써서 여기도 !important 가 필요하다. */
