  Taba documentation.

  The same palette and type as the landing page, laid out for reading rather
  than for selling: one column of text at a measure you can actually read,
  a sidebar that stays put, and no motion. Nothing here is built — it is
  plain CSS served as a file, like apps/landing next door.
