/*
 * CLI DOCS — forge(1)
 * ====================
 * Concept: "A man page someone cared about." The terminal IS the native
 * environment, so monospace dominates. But the tool name in serif gives
 * it authorship — this was crafted, not generated.
 *
 * Hook: The man-page header/footer format (tool(1) / General Commands Manual)
 * grounds it in UNIX tradition. But the typography and color lift it beyond
 * a raw terminal dump.
 *
 * Why Fraunces? A wonky, characterful serif for the display name only.
 * It has personality that contrasts beautifully with the strict mono body.
 * The tool has a name that someone thought about.
 *
 * Why JetBrains Mono? This is CLI docs — the code IS the content.
 * JetBrains Mono is optimized for code readability with distinctive
 * character shapes and coding ligatures.
 *
 * Color: Phosphor green on deep charcoal. Not literal terminal green —
 * warmed up, desaturated. References the terminal without cosplaying it.
