Light through lead, at dusk.

Stained Glass turns the mind palace into a cathedral window. Mottled glass takes your paint and lets it glow from behind; a thick dark came holds every pane, squared off to a two-pixel corner. Rose windows, trefoils, fleurs and quatrefoils are drawn as leading rather than fill. Locked rooms wear an iron hasp.

What it reskins

• The board. A violet cathedral-glass plate in a lead-and-iron frame, panes that bloom under the cursor, and shards of light on every solve.
  
• The palette tray. Every swatch wears the theme's surface and its own motif, so a chip previews exactly what a click will paint.
  
• The connectome map. Spines, node collars and the region rail take on the theme's material and hardware. Region colours stay exactly where they were.
  
• And everywhere else. Navigation rail, tooltips, dialogs, the opening and closing cinematics — the whole palace, not just the board.

Good to know

• Cosmetic only. Not one puzzle, rule, solution or achievement changes. Nothing here makes anything easier or harder.
  
• Switch whenever you like. Settings → Display → Theme, mid-puzzle if you want. Your progress is untouched, and the original paper look is always one click away.
  
• Steam Deck ready. Drawn for the 1280×800 handheld screen and the 1920×1080 desktop window alike, with full reduced-motion support.
  
• Requires Solvizz. This is a theme for the base game — on its own it does nothing.

Same grid. Same rules. Now it is lit from behind.
