/* ==========================================================================
   Ascendant: an observatory plate, not a crystal ball.

   The visual argument of this site is that the astronomy is real and the
   interpretation is editorial, so the design borrows from scientific atlases:
   a dark plate, hairline rules, gilt glyphs, tabular figures, and prose set
   like a journal. Aspect tone is the only place colour carries meaning
   (phosphor green for ease, signal red for friction), and it is used nowhere
   else, so a green line on the wheel always means the same thing.
