/* Pair Desk homepage.
   Concept: the desk itself. The page is the app's warm paper (graphite in dark mode) with its one
   deep-teal accent; the loop in the hero is a dark desktop with three panes side by side: the
   agent's session, the check on the desk, and the game. Pair Desk's status colours are the
   recurring mark: the row of status dots under every section heading follows the life of a check.
   Tokens mirror web/app.css. No external fonts or requests. */
