/* =====================================================================
   Interaction: one system for everything you can click
   - State changes (hover, current, focus): 300ms, one ease-out curve.
   - Surfaces (buttons and cards): the background takes 8% of its own
     foreground colour; a bordered surface's border turns to that colour.
     Nothing lifts, scales or casts a shadow: the system is flat.
   - Press: every surface moves down 1px, in 100ms.
   - Links: a 2px bonk-amber underline that turns to the text colour.
     Menu links go from muted to full colour.
   - Movement (menus, sheets) keeps its own timing: 380ms in, 260ms out.
