 * definition names a key, and only a key written down here resolves to
 * anything. There is no path from a Markdown file to a component nobody chose.
 *
 * `owliver` is deliberately absent — it is not a lucide glyph but the product's
 * own avatar, and the switcher draws it directly. Returning `null` for it is
 * the signal to do that, which keeps the primary agent looking like Owliver
 * rather than like a generic icon.
