/*
 * coder.css - Coder theme for Nicolino
 *
 * Hand-ported from the SCSS sources of hugo-coder
 * (https://github.com/luizdepra/hugo-coder, MIT). Colors become
 * CSS custom properties mapped onto base16 roles when the site
 * enables the base16 feature (with the original palette as
 * fallbacks). Font Awesome icons are replaced by unicode glyphs
 * and inline SVG so no font binaries ship with the theme.
