/* emanix.org — documentation left on the desk
   ================================================================
   Consumes shared/tokens.css exclusively: no colour literal, no
   third-party font request. The six tokens (ground, ground-raise,
   rule, ink-mute, ink, signal) are the entire palette — every rule
   below resolves to one of them.

   This is a technical documentation site. It is deliberately not a
   corridor: no animated rail, no doors, no thesis. It is the manual
   left open on the desk — the face to the distribution's surfaces.
   The spec: "emanix is the documentation left on the desk."

   Two faces carry the thesis: a grotesque for headings, navigation
   and metadata, and a monospace for code and data. The serif is not
   used here — this is not the reading voice.
