High-Fidelity UI Specs & Component Handoff Documentation

The days of manual redline spec PDFs are over. Modern design handoff leverages interactive tools (Figma Dev Mode):

A professional handoff spec includes:

• Design Tokens: Every color, font size, and spacing value references an explicit token name (e.g., spacing.lg, color.text.muted).
• Interaction States: Specs must explicitly show Default, Hover, Focus, Active, Disabled, and Error states for every component.
• Responsive Behavior: How cards wrap, stretch, or hide across standard breakpoints.
