/* ==========================================================================
   harness.css — page-scoped styles for /harness (Saturn AI Desktop).
   Loaded AFTER /assets/css/global.css, which owns every token, the faces,
   the shell and the shared objects (.card .facts .steps .faq .pill .state).
   Nothing here declares a font, a colour literal, a shadow or a gradient:
   every value resolves to a contract token (the legacy short aliases --bg,
   --ink, --surface, --accent, --line resolve to the --saturn-* tokens).
   Depth is hairlines only. One radius: the card radius, 16px.
