/* MetaChimera. CHIMERA's vector-display look: pure black, hairline blue frames, glowing
   single-stroke lettering. Blue is structure, 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. */
