/* 전시회 부스 오디오 가이드 견본 설명(/audioguide/expo) — views/preview_audioguide_expo.ejs 전용 (2026-10-14)
   바탕 글꼴·색·구역 리듬은 audio-guide.css(.ag 토큰)·휴대폰 틀은 qr-phone.css 를 그대로 쓰고, 여기는 이 페이지만의 칸.
   ① 찍어 볼 QR  ② 실제 관람객 화면(iframe — 진짜 /audioguide/expo/tour 를 휴대폰 틀 안에 줄여 띄움)  ③ 목소리 견본 표
   ④ 운영자 화면(실제 화면 캡처 + 견본 운영자 화면 /audioguide/expo/admin 으로)  ⑤ 만들고 고치는 순서
   ⑥ 비용(맞춤 견적 없음 — 이 견본에 든 글자 × 요금제)  ⑦ 질문  ⑧ 시작
   바탕은 구역마다 번갈아: 흰 → 회색 → 흰 → 옅은 회색 → 흰 → 회색(비용) → 흰(질문) → 연보라(시작) */
