/*
  site-modern.css
  Reusable stylesheet for the redesigned kanko-hofu.gr.jp pages.

  How to use:
  1) Place this file at a shared path (example: /css/site-modern.css)
  2) In each HTML page, include:
     <link rel="stylesheet" href="/css/site-modern.css">
  3) Remove the old bootstrap/custom/theme CSS links for those pages (optional but recommended).

  Notes:
  - Uses Juma default brand tokens (accent #40C4D3).
  - Designed for content pages: header + hero + toc + article + share + footer.
