/* ============================================================
   KOKORO — SHARED SHELL (header + footer)
   Persistent navigation chrome that appears IDENTICALLY on both
   mykokoro.jp and kokorostore.jp. The only difference between the
   two is the action area on the right:
     · brand site  → quiet "ストア →" text link (no loud buy button)
     · store site  → "ブランド" back-link + shopping bag w/ count
   Everything else — logo, font, spacing, glass blur — is shared.
