/* view: the universe ------------------------------------------------------
 * One map of every person (a star) and every song (a place), on its own dark
 * field. The sky is one canvas the view draws (views/universe.js
 * `painterOf`, listen/skymarks.js for each mark's colour, opacity and size):
 * this sheet gives it its box, the stage's star size (--u-dot) and the
 * colours it reads (listen.css's --sky-* tokens). Names are HTML links over
 * the sky. The head sits
 * above the sky (the way back, Since last look and the key's "i" on one row,
 * then the counts and what the map is), so a framing never puts a star under
 * its words. Tokens are listen.css's (the --sky-* set); nothing here defines
 * a colour. The dock's reserve on #view stays: the stage's height leaves room
 * for it. A wide screen (≥ 900px, Desktop 2c) holds the same parts in the
 * 1200 column, the stage at most 620 tall.
