I used Stitch as the primary design and generation tool throughout. Workflow: (1) Uploaded the official FIFA 2026 design system as a
design.md file, (2) Used streaming generation to build all 6 screens iteratively on the canvas, (3) Used in-place AI edits to redesign components - most notably the cyberpunk → FIFA broadcast redesign of the home hero, (4) Connected Stitch via StitchMCP to Antigravity to programmatically generate and edit screens via the MCP API - - used edit_screen, get_screen tools to automate multi-screen updates simultaneously, enabling batch edits across all pages without touching Stitch manually, (5) Used edit_screen again to iterate on the design layer directly through MCP - refining match cards, the knockout bracket, and player card layouts programmatically, (6) Used native HTML canvas and CSS animations for the bracket connector lines and motion design throughout.
