Writing-style rules for any prose authored in this project — READMEs, design docs in browser-plan/, commit bodies, PR descriptions, status updates. USE WHEN about to write or edit prose (Markdown text, doc comments meant for humans, commit messages, PR bodies), or when reviewing prose for tone. Enforces: fifth-grade reading level (short sentences, common words), no semicolons unless truly required, no unclear abbreviations (spell out PSL, ALPN, HSTS, TDZ, SSIM, GA/gtag, VM, GC on first use), no verbose restating, no pointing out the obvious. Project-specific naming: never use the phrase 'hand-written' — name the Starling resource explicitly ('Starling JS engine', 'Starling DOM', 'Starling networking'). DO NOT USE FOR: code logic, identifier naming, or test assertions — only human-facing prose.
