{#-
  Light/dark switcher styled after the search button of the Zensical modern
  variant: a square host (1.6rem, 0.4rem corner radius, faint fg--lightest
  fill, hover fg--lighter) holding a single animated sun/moon glyph. The glyph
  is a sun whose core scales up while a mask circle slides in to carve the
  crescent and the beams fade out — the scheme change drives the whole morph
  from CSS alone. The palette <input>s and their <label> click targets keep
  the markup that the Zensical palette JS expects: every input is followed by
  its label, and the JS unhides the label of the active palette and reacts to
  radio change events. The visible control is a persistent sibling, so the
  glyph morphs in place instead of the whole button being swapped.
