/* MetaChimera. CHIMERA's vector-display look: pure black, hairline frames, glowing
   single-stroke lettering. One colour is structure, and it is the colour of the section being
   browsed (blue at home); amber is sound (whatever is playing, and the controls that play it).
   No fills, no rounded corners.

   Written phone first: the list is the page, the player docks at the bottom, the stage is a
   full-screen layer. From 900px the same list becomes a sidebar with the stage beside it. */
