/* Parallax Maze Puzzle — docked description panel + screenshot gallery.
   Same shell as the Ghostnote and Pacmanic pages (arcade tokens, collapsible
   left panel). There is no web build to embed, so the stage is a scrolling
   column of screenshots instead of an iframe. Like those pages this one loads
   no shared stylesheet, so the tokens are restated here under the same names
   as site.css. */
