/* The player is drawn in greys like the sequencer: every colour has equal red, green
   and blue (test/grayscale.test.ts refuses any other). A compact, bevelled skin over a
   dark display, after the desktop players of old.

   These styles apply inside the player's shadow root (src/shell.ts), and only there.
   The shell gives the host element `all: initial`, so no property the host page sets
   reaches the player. Custom properties outlast `all`, so the palette is defined on
   the root's top-level elements (.frame, .failure), below the host element, where they
   also set its type and colours. */
