 * Mixed theme (CRO study, 29-09): black only for the hero, CTA bands and the
 * app band; everything with long text, screenshots and prices on white, like
 * the CRM itself. Yellow is a BUTTON with black text (15:1), never text on
 * white (1.4:1); on white a yellow button gets a dark edge (WCAG 1.4.11). */
