/**
 * Home Page — Categories Section
 *
 * 3-column grid of category cards. On hover a card expands to
 * double width, revealing the 2 latest posts + article count.
 * Last-column cards expand left instead of right.
 *
 * Architecture:
 *   .home-cat-card          → grid cell, relative context
 *   .home-cat-card__inner   → the visible card (grows on hover)
 *   .home-cat-card__default → always-visible content
 *   .home-cat-card__preview → revealed on hover (latest posts)
 *
 * Dependencies: home-base.css, child theme design tokens
 *
 * @package BlockskyChild
