Solvizz: Cold Steel Theme

The palace, machined.

Cold Steel strips the paper away and bolts the mind palace to a workbench. Cells square off to a hard zero-radius corner with an outer bevel and a rivet at each one; brushed-steel grain runs horizontally under the paint. Hex bolts, hazard chevrons, gear teeth and rivet heads mark the corners. Locked rooms are bolted shut.

What it reskins

• The board. Welded diamond plate inside an angle-iron frame, rivets at every corner, and a spark where your cursor lands.
• 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.
  

Nothing softer about it. Just the grid, the rules, and a great deal of steel.
