/* ============================================================================
   Mancube — capability register
   ----------------------------------------------------------------------------
   One stylesheet, no framework, no build step, no runtime network request. The
   fonts are vendored next to this file, so the page renders identically on a
   conference wifi that resolves nothing.

   The world is a printed capability register: hairline rules edge to edge, a
   mono index in the left gutter, and every claim sitting in a row next to the
   thing that proves it. Deep petrol is the only saturated colour on the page —
   it marks evidence and nothing else, so "this is checkable" is legible before
   a word is read.
   ============================================================================ */
