   IDATSUKA — v4 墨と真鍮 / Sumi & Brass
   Night (default) is warm black with one brass accent.
   Day (data-theme="light") is not the night recoloured:
   white paper, daylight photographs, matted images and
   vermilion seals — see "昼 / DAY" near the end.
   Every rule reads tokens; token names are kept from v3
   so the pages' own <style> blocks keep working.
