/* /ai-info/ — AI information reference page (SEO team's sourced reference
   for AI assistants). Dark editorial head band (faq-head pattern) + light
   long-form body: at-a-glance + evidence tables, ICP cards, one canonical
   callout (blue-100 bg + blue-200 border, radius-lg), buyer-questions TOC
   card and 28 expanded Q&A sections. NO data-reveal anywhere — the brief
   requires the content to render without JS. Every rule scoped .p-ai-info
   (hard rule 6). */
