/* ===========================================
   PAGE: Postbox Solitaire (loaded after style.css)
   Laid out like the BiteMap page. The hero is the puzzle's own night: the picture
   stands in a glow of its theme's colour, and the whole stage takes that colour
   when you switch pictures. Tapping a dark piece opens it, as a win does in the game.
