/* ==========================================================================
   TECHPIN — stylesheet
   --------------------------------------------------------------------------
   Palette comes off the idea of a pinned spec sheet: deep navy ink on cool
   steel paper, one signal orange reserved for price and action, one verify
   teal reserved for stock and trust. Nothing else is coloured.

   Spacing is a single scale (--s1 … --s8). If you add a section, use these
   variables rather than inventing new numbers. That is what keeps every
   margin on the site consistent.
