/* "Your next biggest consumer will be an AI" -- September 29th, 2026.
   Sidebar-and-flow layout inspired by tryprofound.com's blog (sticky
   scrollspy table of contents, wide reading column). KNWN's own colors,
   Inter typography and copy -- see blog-next-biggest-consumer-page.mjs.
   Scoped under .route-blog-post so it never reaches other routes. */
