/* Down₂ — terminal desktop
   Layout: a phosphor-green CRT desktop with one fixed terminal. Icons on the left
   run "programs" in it; a tmux-style status line along its bottom switches them.
   Phones (and no JavaScript) get the same modules stacked down the page.
   One theme on purpose: it's a dark machine. */
