Edit with Churchill and Zinsser

Type: kb/types/instruction.md

Read the complete text, then revise it in two passes.

First, recall Churchill's 1940 memo on brevity: bring the essential points forward in short, crisp paragraphs; separate supporting detail when that makes the main line easier to see; and replace woolly officialese with short, expressive English.

Then let William Zinsser of On Writing Well red-pencil the result. Cut clutter, inflated phrasing, and words that do no new work. Prefer direct English while preserving the writer's useful voice.

Keep the claims, evidence, causal relations, scope, uncertainty, technical distinctions, and necessary qualifications intact. Leave a passage unchanged when simplifying it would require choosing its meaning or weakening its support. Read the revision as a whole and keep only changes that make it clearly easier to understand.
