/* Hidden Weights — one stylesheet.
   Concept: a warm, tactile miniature workshop. Walnut and brass under a low
   light from the upper left; two-layer shadows (contact + diffuse). Light: cream
   paper and warm ink; dark: a deep blue-grey evening with darker wood and
   brighter brass. Objects are domed weights in six colours, each with a letter
   and a symbol; reference weights are engraved brass cylinders.
   Type: the system's rounded face, tabular numbers. Motion: springy, physical. */
