/* The E4 Mafia Network: one stylesheet for the Ticket Desk, the Lab Bench
   and the Service Map. The layout is the one the owner chose (C with A's
   bars, 11 October 2026): the three view buttons, the Lab Bench bars across
   the page and pinned to the top, then three columns: the left column
   (queue, shelves or map), the ticket, and the terminal pinned on the right.
   Contrast is WCAG AAA (7:1 body, 4.5:1 large), checked on painted pixels. */
