/* ===========================================================================
   Homepage only.
   Lifted verbatim out of the HOME_STYLES template literal in app/page.tsx, so
   the styles live where every other stylesheet in this project lives and get
   the same content-hashed cache busting from cssHashes() in next.config.ts.
   Nothing here is global on purpose: .hero, .basic, .cat-chip and
   .handoff-strip are generic enough that putting them in site.css would start
   styling pages that have never seen them. Loaded only by app/page.tsx, after
   lessons.css, which is the order the inline <style> block had by virtue of
   sitting in the body.
