/* Round 23: the H06 hub-and-ring figure (ring16 + ending D "lights on") on the round 21 page,
   in light (K1 warm paper) and dark. Only colour tokens change between the two; the figure code is
   the same files h16-06d.html uses (figures/kernel.js, kit610.js, ring16.js, ring16-d.js).

   How the figure is coloured (same idea as Hairline): every solid is filled with the page colour so
   nearer shapes hide farther ones, and strokes come in three tones plus the one orange:
     base  the normal line          --r-base
     m     the dim inner creases     --r-dim
     hi    the bright, "lit" line    --r-hi   (labels light to this too)  */
