/**
 * article-shell.css — base layout for SmartMowBot blog / article pages
 *
 * Design tokens are SmartMowBot's own, taken from index.html <style id="smb-home">
 * and assets/css/global.css:
 *   #16A34A turf green (primary)   · #15803D deep green (text-on-white, hovers)
 *   #1F2937 ground (ink / dark surface) · #111827 · #0F172A (topbar+footer deep)
 *   #FACC15 CTA yellow (backgrounds on light, text only on dark) · #EAB308 hover
 *   #E2E5DE line · #F5F7F4 wash · #6B7280 muted · #4B5563 body
 *   Archivo (headings, 500-900) + Inter (body, 400-700)
 *
 * Contrast rule for this palette: #FACC15 is 1.6:1 on white — it is NEVER used as
 * text on a light surface here, only as a filled background or as text on #1F2937.
 * Small text on white uses #15803D (4.9:1), not #16A34A (3.2:1).
