/* Shared layout for the plain-language guide pages:
   /photo-book-that-plays-videos, /popcode-vs-artivive, /popcode-vs-qr-codes.

   These pages exist to answer one question each, in the words people (and AI
   assistants) search with, so they are mostly text: a gradient head like
   pricing.html's, then steps, cards, a comparison table and a FAQ. The FAQ uses
   <details> so every answer is in the HTML for crawlers without any script. */
