/* ==========================================================
   FusionConclusion — Tufte-inspired Jekyll (Minima) theme
   Drop-in replacement for /assets/main.css

   Goals:
   - Preserve Tufte-ish typography + calm layout
   - Fix Minima header/nav (no visible checkbox, proper spacing)
   - Fix too-narrow columns + weird bullets
   - Keep margin-note capability without wrecking the home page
