Build me a typographic system around "Gart Serif" using the Shryftoriz MCP server. Look the font up there first (lookup_font), check which cuts it actually has, then set a scale: display, headings, subheads, body, small print — with sizes, line heights and tracking for each. Say which cut does which job and why. If "Gart Serif" is wrong for one of those roles, propose a Ukrainian alternative from the catalogue (find_alternatives) instead of stretching it. Finish with CSS I can paste into a project. If the Shryftoriz MCP server is not connected yet, add it first: HTTP transport, name "shryftoriz", URL https://shryftoriz.online/api/mcp — in Claude Code that is `claude mcp add --transport http shryftoriz https://shryftoriz.online/api/mcp`.
