/*
 * Blog Listing Styles (blog-index.css)
 * =====================================
 *
 * Layout: Minimalist editorial grid — Riverside-inspired
 *
 * STRUCTURE:
 *   [Thin hero bar]              — .fit-blog-hero (single line, brand accent)
 *   [Featured post | Sidebar  ]  — 1st card (large left) + cards 2–4 (compact right)
 *   [Standard listing cards   ]  — cards 5+ (horizontal 25/75 media object)
 *
 * PHILOSOPHY: Whitespace over borders. Typography over decoration.
 * Only .md-post--excerpt (Material's listing class) is targeted.
 * Full post pages are completely unaffected.
 *
 * NOTE: -webkit-line-clamp used intentionally for cross-browser line clamping.
