   COLOR is defined here and owned here. This file is the only source for the
   site palette, with no external stylesheet to keep in sync with.

   SURFACE TREATMENT: translucent borders and generous radii, which read better
   on a dark ground than fixed grey hairlines.

   Layout concept: "the matrix is the map". Structure borrows from an ATT&CK
   coverage matrix, the native artifact of this business.
