/* ふうふ旅 — Tours with Ryo & Maria
   Built from Ryo & Maria's own material:
   - accent orange  = the Hamarain BOOKS opening flyer (and Maria's orange jacket)
   - black labels   = the caption style of their reels ("4 years since the wedding")
   - station stamps = the eki-stamp habit of Japanese travel, one per stop of their route
   Japanese principles: 間 ma (space), 簡素 kanso (few colours/typefaces),
   不均整 fukinsei (asymmetry), 渋み shibui (muted palette), 縦書き tategaki, 青海波 seigaiha.
