make fmt and make fmt-check now cover the Markdown files with prettier as well as the Go source: prettier 3.8.1 pinned in package.json and yarn.lock, four-space indents and proseWrap always in .prettierrc, all three copied unchanged from the sneak/prompts templates. script/bootstrap adds pinned node (through nvm from a hash-checked archive when none is installed), yarn and prettier after the pinned Go. README.md is reformatted by make fmt and its Entrypoints section says what each step needs.
Model: opus-5-5
