   AUTOLINK COMPONENTS — the two /ad-accounts sections, shared.
   1. HOW IT WORKS timeline  (.hiw-*)   → docs/partials/hiw.html
   2. COMPARISON TABLE       (.cmp-*)   → docs/partials/cmp.html
   Load AFTER core.css (and before page CSS):
     <link rel="stylesheet" href="assets/css/components.css" />
     <script src="assets/js/components.js" defer></script>   (after core.js)
   The rules below are copied 1:1 from ad-accounts.html (inline <style>) so the
   look is literally the same code. ad-accounts.html itself does NOT load this
   file — if you change a rule here, change it there too (and vice versa).
   Only additions vs. the original: section wrappers (.hiw-section /
   .cmp-section), the `.site` text-wrap resets, `.hiw-meta[hidden]`, and the
   reduced-motion block at the end. Demo: /docs/components-demo
   Read docs/DESIGN-LESSONS.md before changing anything here.
