NON-NEGOTIABLE CONDITIONS: FIXED BUDGET: Total budget is strictly $800 across 4 milestones. Do NOT apply if you intend to renegotiate the scope or price later. NO DESIGN WORK: All UI components, layouts, and design systems are pre-provided via our licensed Tailwind UI package. Your role is technical logic, database architecture, and API integration.

Milestone 2 ($250): Visual garment configurator, dynamic price engine, and measurement profile module.
