   Knuddels Beach — stylesheet
   ----------------------------------------------------------------------------------------------
   Layout model: #app is a 4:3 box (800 × 600 world units) that fills as much of the viewport as
   possible and is letterboxed on a dark page. One world unit is exposed as the custom property
   --u (a CSS length). CSS computes it from the viewport as a fallback; ui.js overwrites it with
   the measured clientWidth / 800 on every resize. Everything inside the box is positioned in
   percentages and sized in multiples of --u so the DOM scales exactly like the canvas.

   Look: the classic Java-Swing / Windows-classic beige of the original Knuddels applet — beige
   boxes, thin olive borders, 1px inset highlights, Arial 13px, chunky scrollbars.
