/**
 * Custom Blog Grid — front-end styles.
 *
 * Built to the approved journal design. Colours are sampled from it:
 *   background #F2F1ED · ink #101410 · label green #17794A · dot #2BB36B
 *   body copy #535652 · meta #616460 · archive link #4F514E · mark #DEEAE0
 *
 * Everything is scoped under .custom-blog-grid so nothing leaks into the
 * surrounding theme. Sizes are fluid (clamp + vw) so the section keeps the
 * design's proportions from a 1280px container up to a 2560px one.
 *
 * The four palette values are injected as custom properties from the settings
 * screen; the rest can be overridden in a theme stylesheet, for example:
 *
 *   .custom-blog-grid { --cbg-radius: 0; --cbg-gap: 2rem; }
 *
 * @package CustomBlogGrid
