_Content coming soon._ The interlude will distinguish configurable run-envelope budgets from
fixed physical limits, teach top-level `override` directives, and show how list, geometry,
chalk, operation, and stitch budgets reveal algorithmic trouble.

<Run>{`// A design that stays well within budgets
seed 42
repeat 20 [
  let r = repcount * 2
  repeat 36 [ fd (r * 0.175) rt 10 ]
]`}</Run>
