/* ── Maverick board ─────────────────────────────────────────────────────────
   These classes were used by renderMaverick() before they existed. The board
   rendered its data correctly and looked broken: "2computer(s)" with the
   number welded to its label, because <b> and <span> had no styling to
   separate them. Caught by screenshotting the page rather than by checking
   that the endpoint returned 200 — an API test would have passed all day.
   Uses the existing theme variables so the board cannot drift from the rest
   of the UI when the palette changes.                                        */
