_Content coming soon._ This chapter now starts with the top-level `plan 'nearest'` and
`plan 'reversing-nearest'` directives, explains their colour-block and explicit-trim barriers,
then compares post-run planning with explicit `route`/`routepaths` ordering in source.

<Run>{`// Motifs drawn in a sweep order to minimize jumps
for x = (-3) to 3 [
  for y = (-3) to 3 [
    up  moveto (x * 10) (y * 10)  down
    repeat 4 [ fd 3 rt 90 ]
  ]
]`}</Run>
