/* Hollow Reign is authored portrait. On a phone, and on any viewport that is
   taller than it is wide, the canvas simply fills the screen. On a desktop
   window it must NOT stretch to 16:9 — every screen in the game is a vertical
   column, and a wide canvas renders that column as a thin strip of tiny text
   across the middle of a very large window.

   So on wide viewports the canvas takes the full height and a phone's aspect,
   centred, with the page's own gradient behind it. That is a deliberate frame,
   not the stock template's letterbox: the stock page pinned a fixed 960x600
   pixel box to the middle of a white document regardless of window size. This
   is responsive, aspect-correct, and the same dark field as the game. */
