/* Hallmark · genre: playful · component: site search ("the typewriter") · theme: custom (site tokens) · tone: playful-bold
 * Loaded on every page (header.php), with search.js.
 * idea: searching is typing. A sheet feeds out of the roller of a Tiga Titik typewriter, you
 * type on it, and the answers are typed back line by line — then the bell. The machine's keys
 * go down as you type. On phones only the sheet shows.
 * type: Courier Prime (the typewriter) on the paper; Anton on the name plate.
