/* ==========================================================================
   Shared tool-page components: the test card, numbered steps, bulleted
   lists, connection flow diagram and activity table reused across every
   tool and guide page (speed tests, ping/jitter/packet-loss tests, WHOIS,
   DNS lookup, port checker, calculators, guides…), loaded once alongside
   each page's own stylesheet. Reuses the design tokens from main.css
   (colors, radii, shadows, type) — no new palette.
