/**
 * FAQ terminal: a playful, machine-readable FAQ.
 *
 * The FAQ lives as semantic <dl> content (crawlable + FAQPage schema) styled to
 * look like a terminal transcript. A floating "> _" button opens an interactive
 * command palette that runs the same commands, reading answers from that same DOM.
 * All colours come from the design tokens in tokens.css.
