Create a 5.5x3 landscape app-mockup poster for an app called "{appName}", which is {purpose}. Design system style: {aesthetic}. Show 4 phone screens laid out left-to-right in a unified composition: (1) a welcome screen with the wordmark "{appName}" and a single line of copy — no photography, no illustration, just type and a soft accent shape; (2) a clean home screen with the primary card/list pattern for this product; (3) a product or service detail screen; (4) a second product/service screen showing a different state or flow. All four screens share the same design language and color palette. Strong unified design system. No external elements outside the four phone frames. Clean shadow under each phone, single cohesive background, minimal grid alignment. Design-portfolio-quality poster.
