/* BLOG POST v5 — light foundation. The per-article inline <style> template
   still carries dark hardcoded values; the `body `-prefixed rules below beat
   them on specificity (0,1,1 vs 0,1,0) regardless of source order, so ONE
   file converts all 19 articles. Keep this stylesheet render-blocking — it
   holds the :root tokens the inline critical CSS depends on (FOUC otherwise). */
