/* 오카리나편.
   THESIS: 넓은 자연 + 오래된 유적 + 그 안에 숨은 고대 기술. 수채화 풍경 아래 지도 종이를 펴고,
   연주 도구는 오래된 돌판에 새긴다. 돌판 안의 시안 빛은 누르거나 지금 부는 음에만 희미하게 켜진다.
   OWN-WORLD: 지도 종이 바탕과 종이 결, 얇은 이중 테두리에 모서리를 깎은 판, 유적 석재 머리띠,
   하늘 청록 유약 오카리나, 금빛 나무. 둥근 카드·그림자·그라데이션 글자는 쓰지 않는다.
   반복 모티프는 직접 만든 바람 문양(구멍 하나에서 퍼지는 소리 물결). 트라이포스·고대 문자는 쓰지 않는다.
   간격 4 8 12 16 24 32 48 64 96, 글자 12 14 16 18 20 24 30 36 48. 색은 아래 토큰만 쓴다. */
