/* apps/invite/style.css — 할로윈 파티 초대장 만들기: 밤보라 + 호박 주황 + 촛불 노랑.
 * 모바일 한 줄(--app-width 480px). 글꼴은 언어 파일 fonts → :root 변수(--font-display 등, 생성기가 이 파일 뒤에 둔다).
 * 공통 타이틀 바(G.topBar)·끝 화면(data-mg-end)은 --mg-* 변수로만 색을 맞춘다.
 * 초대장 그림은 canvas(invite.js) — 둥둥 떠다니는 시작 화면 이모지(.iv-hero)는 prefers-reduced-motion 이면 멈춘다.
