/* ==========================================================================
   Logs section — page-specific layout only.

   Adds the change-log entry and version-navigation layout on top of the
   vendored theme. Everything here uses the theme's own design tokens
   (styles/main/style.css); no colour, radius, or spacing value is hard-coded,
   so the section inherits any future retheme. See DESIGN.md.
