   Puffer Reef - game-specific styles.

   Loaded after /assets/base.css, which supplies the design tokens,
   the top bar, the buttons, the footer, the modals, the cookie
   banner and the legal-page layout shared by every Lynxy game.
   Only the field, its screens and the controls live here. The
   field itself is drawn on a canvas by game.js, which reads
   --stage-mode to switch between daylight and deep water.
