/* ==========================================================================
   Hyrule skin — custom theme layer for taoranl2.github.io
   Loaded after main.css so it overrides the Minimal Mistakes defaults.

   Original artwork and styling inspired by the look and feel of open-world
   adventure games (parchment maps, glowing runes, rolling hills). No
   third-party character art, logos, or assets are used or reproduced.

   Plain CSS on purpose: GitHub Pages copies this file verbatim, so a typo
   can never break the Jekyll build.
