Plain English rewriter

Rewrite this in plain English:

{{text}}

Rules: 8th-grade reading level, replace jargon with the actual concept, keep technical terms only when there's no plain alternative, break long sentences, use active voice, cut hedge words ('basically', 'essentially', 'really'). Don't dumb it down — preserve every fact and nuance. Output the rewrite, then list any terms you replaced and what they were replaced with.
