/* ──────────────────────────────────────────────────────────────────
   ImageForge design system
   Shared tokens + components for the hub and every project workflow.

   Design rules (see CLAUDE.md):
   • No pills. Text buttons are rounded rectangles — border-radius: 6px.
     Circular icon buttons (toggles, dots) are the only exception.
   • Warm paper palette, quiet type, generous spacing.
