/* /freetts 「음성 하나로, 여기까지 됩니다.」 기능 구역 (2026-10-02 개편)
   마크업 = views/include/freetts_features_section.ejs · 움직임·소리 = freetts-features.js

   구성: 왼쪽 = 스튜디오 왼쪽 메뉴와 같은 도구 목록(아이콘·이름 + "무엇 → 무엇"), 오른쪽 = 고른 도구의 작업 화면(실제 화면을 줄여 그림),
         아래 = 그 도구의 설명 한 벌(제목·두 줄·핵심 세 가지·버튼). 도구 여섯 개가 모두 같은 틀이다.
   원칙: 아이콘 네모 카드·그라데이션·배경에서 혼자 도는 장식 없음. 움직임은 탭을 고르거나 재생을 누를 때만.
         작업 화면의 색은 실제 스튜디오와 같다 — 믹서 트랙 음성 하늘색·배경음악 초록, 재생선 빨강, 확장자 딱지 MP4 보라·PDF 장미·SRT 회색.
   주의: v2.css 가 구역 안 h3 를 24px 로, article h3 를 18px 로 덮는다 — 작업 화면 안에는 h3·article 을 쓰지 않는다. */
