/* Fieldcraft portfolio kit — the base every theme builds on.

   One markup vocabulary (pk-*) for every example portfolio; a theme in
   themes/<name>.css re-dresses it — colours, type, layout — so any example can
   be shown in any theme (?t=<name>, see kit.js). This file on its own is a
   calm, light, neutral site. Every visual is CSS: project covers are drawn
   from two colours per project (--c1, --c2) and a data-kind pattern.

   Themes should restyle through the custom properties first and only
   override selectors when the layout itself changes. */
