   7Compactification from 10 to 4 macroscopic dimensions removes 6 = 10−4
   8internal directions. In RS framing, 6 = 3 colour axes + 2 weak axes +
   91 hypercharge = cube face count (= rank sum 3+2+1 of B₃).

  11Five canonical compactification families (= configDim D = 5):
  12  Calabi-Yau, torus, orbifold, warped (RS1/RS2), brane-world.
