/* Picture Logic (logic.html, logicapp.js), on top of style.css: the slide puzzle's one-screen layout
   (.slide-app: head, status, stage, actions; More panel; level pills), so it never scrolls. The board
   is the clue column, the clue row and the grid, sized from the stage (a size container), with thicker
   lines every 5 squares. Filled squares are ink on cream (light) or cream on evergreen (dark); the
   picture's own colours show only once it's solved. As the approved mockups (previews/games/picture-logic). */
