/* West-East Connection — site v1
   Layout: one centered editorial column on paper; sticky header, page sections
   divided by hairline rules, ink contact band before the footer.
   The Brand Guide defines no dark variant, so the site commits to one lit
   paper/ink world (like a printed worksheet) rather than inverting it. */
