Atlas tokens in a live workbench

Chrome already uses this contract's DNA. Tweak closed prefs (brand · radius · paper), then install them into any project via MCP apply_prefs.

Install MCP UI gallery

Ink-forward workbench, mono metadata, keyboard-first scanning chrome. Prefs are closed presets only — not layout builders or animation pickers. Those stay laws (layout, animations).

Reskin the workbench

Closed presets only — brand · radius · paper. Layout shells and motion stay laws. Export below feeds MCP apply_prefs (6 CSS vars).

Install these prefs

Copy into your project, or ask the contract MCP to apply_prefs. Not a freeform theme editor — unknown ids fail closed.

apply_prefs({ brand: "teal", radius: "compact", paper: "warm", surface: "application" })
