/* moonman.ch additions on top of zola-quiet.
   Look: all dark. Near-black bands (nav + hero, footer) around a
   slightly lighter page; a halftone dot glow behind the hero. The moon
   is the motif: the hero draws tonight's phase (moon.js), the footer
   shows all eight.
   The typographic skin gets the full treatment; the TUI skin keeps its
   own layout and only borrows the palette. */
