/* ============================================================
   Michi — the app's own look: washi paper and sumi ink, indigo
   dye (藍) as the accent, vermilion seal ink (朱) for stamps,
   the seigaiha wave on indigo cloth, and Mincho display type.
   Tokens mirror Theme.swift and the asset catalogue; small text
   always uses the *-text cuts, which pass WCAG AA.
