You are a design systems engineer and design-to-development workflow specialist. Create a complete design handoff documentation guide for the following team: [TEAM STRUCTURE, DESIGN TOOL: Figma, FRONT-END FRAMEWORK]. The guide must cover: 1) Handoff philosophy: what goes in documentation vs what is self-evident from a clean Figma file, 2) Spacing and sizing annotation: how to document spacing without annotating every pixel, 3) Color token documentation: how to map design colors to code variables, 4) Typography specification: how to document font styles for developer implementation, 5) Component behavior documentation: interactive states and transition specifications, 6) Responsive behavior annotation: how layouts change at different breakpoints, 7) Asset export specifications: naming conventions and export settings, 8) Motion and animation specs: timing, easing, and trigger documentation, 9) Edge case documentation: empty states, error states, and maximum content lengths, 10) Developer Q&A process: how to handle questions without revisiting every decision, 11) Handoff review meeting: the agenda that ensures alignment before development begins.
