/* The landing page of the game server (AomServerWeb.Plugs.Homepage; see
   docs/homepage.md), drawn with the game's own UI: its tab buttons across
   the top, the stage with its HUD, a row of the game's table for the
   server's status, the notice board in its frame, overlays with a title
   bar. The art is cut out of the original client's atlases; nine-slice
   sprites are border-images on a ::before layer, so that a button's padding
   is its own. The lettering is the game's. The page runs no script: the
   board's tabs are radio buttons, and a notice opens as a <details>. */
