  Nightshade docs, v2. A field-guide take on a conventional docs layout:
  sticky header, grouped sidebar, ~72ch reading column, "On this page" rail.
  Identity: midnight violet and parchment, a calyx-and-stem rule above each
  section, specimen frames with crop marks around code and output, a herbarium
  label on rule pages. Dark values on :root; light under the two light guards.
