   The Second Brain — product page
   Self-contained by design: every page keeps its own stylesheet.
   The product-page foundation (type, sections, buttons, the
   product-UI kit, chat, FAQ) is copied from the Customer OS page
   so the two read as one system; blocks only this page uses are
   prefixed .sb-.
   Loaded after /index.css (palette, fonts, nav, footer, --u).
     --u  page layout and type
     --k  the inside of a product screen (= --u on desktop,
          fixed below 1180px)
