   Long-form project pages (agentic-delivery.html). Two audiences at once:
   a plain-English sentence carries each section, and the technical detail
   sits under it in a .detail block that reads as subordinate.

   Every colour here is an existing token — no new ones. Two deliberate
   choices worth knowing:

   1. .detail is marked by a hairline rule rather than a filled panel. It
      keeps the page quiet, and it keeps --text-faint on the page ground,
      where it measures 4.65:1 light / 4.62:1 dark. On --bg-raised that same
      token drops to 4.24:1 in dark mode and misses AA, so faint text is
      never placed on a raised ground here.
   2. No accent colour is spent on these components. Per BRAND.md the ember
      appears once per view, and on this page that is the brand mark.        */
