 * GOODIE vouchery – společný vzhled s GOODIE Gap, Chat a Product board
 * (návrh GOODIE UI v1.1): tmavý teplý rám, v něm světlá pracovní plocha
 * jako list se zaoblenými rohy, bílé karty, zlatá jen jako výplň
 * (text na ní je tmavý), odkazy modré. Písmo Inter, základ 13 px,
 * kompaktní řádky, tlačítka jako malé pilulky.
 * Kiosek používá stejné prvky, jen s většími dotykovými plochami.
