/* PLAN 349 sub7 헬퍼 — 페이지 계산 묶음이 조작 하나에 한 번만 도는지 · 열기만 하면 저장 측점 목록 그대로인지.
 * 진짜 TS(`design_pipeline_page` · 단계 파일 전부)를 트랜스파일해 Node 로 돌림 · 서버 창구만 가짜.
 * 종단 보기 고리(가게 stations → 상세 갈아끼움 → 종단도 render · 비정규 측점 · 유토곡선 설정)를 흉내 냄 —

 * 입력 argv[2] JSON · argv[3] 격자 이진. 결과 = 표준출력 JSON. 짝 = `test_349_pipeline_once.py`. */
