   Pabst Interference — PRIMITIVES
   --------------------------------------------------------------------------
   The nine values this identity is made of, and nothing else. No semantics
   live here: a primitive says WHAT A COLOUR IS, never what it means. Roles are
   bound in tokens.css, per property.

   THIS FILE IS SHARED. A byte-identical copy lives in the projections suite
   (ff-algo). The two properties bind these to different roles - red is the ink
   the badge is printed in here, and the data exception there - but they are
   printed with the same inks. If these two files ever diverge, the family is
   over; tests/test_primitives.py fails the build when they do.

   PROVENANCE. Every value except the two ambers is sampled from
   img/pabst-interference-logo.png (836x842, md5 5136bb34a4847a6aa7f04344a9a33e66),
   measured pixel by pixel at alpha >= 128 over 552,796 opaque pixels.
   See SITE_REDESIGN_PLAN.md 1.1-1.3.
