   KOKORO — SHARED DESIGN TOKENS
   The single source of truth imported by BOTH mykokoro.jp and
   kokorostore.jp. This is what makes two sites read as one brand:
   identical colour, type, motion, radius, shadow.
   Do not fork this file per-site. Site-specific look comes from
   how these tokens are *composed*, not from changing the tokens.
