/* =============================================================================
   Aixly — site.css
   -----------------------------------------------------------------------------
   DIRECTION: engineering drawing. Not a decoration — the provenance is the
   product. An MES sits between a print and a machine, so the page is built like
   a drawing sheet: a blueprint grid under everything, corner ticks on every
   frame, a title block in the hero, numbered figure captions under each
   screenshot, and IBM Plex Mono carrying every label the way a drawing's
   annotations are lettered differently from its title.

   Committed by Brent Lavitt in blavitt3/aixly; preserved here token for token.
   This is NOT the place to reach for a different look — the tokens below are
   the brand until the client says otherwise.
