/* ==========================================================================
   theme.css — SYNC design system
   Minimal · monochrome · flat · typographic.

   Principles:
   - Hierarchy comes from type, spacing and alignment — not colour or shadow.
   - Surfaces are flat. Separation is a 1px border, never elevation.
   - Colour is reserved for status. Everything else is the neutral ramp.
   - One 8px spacing scale, one radius, one border. No exceptions per page.
