Use when a single-file HTML technical document should carry a dark developer / terminal aesthetic — monospace, terminal-green on near-black. Trigger on: "dark terminal doc", "terminal-style HTML", "developer-terminal aesthetic", "make it look like a terminal", "dark developer-facing HTML page", or a comparison table, reference sheet, changelog, release notes or API cheatsheet in that look, or one matching a document already in this style. Not for a doc with no stated aesthetic.
