Square Korean health-management information card designed for older adults, shown as a clean front-and-back card mockup on a pale mint background. Large readable visual hierarchy with simple icon zones for heart health, medication schedule, emergency contact, walking activity, and clinic visits; warm coral and navy accents, rounded corners, generous spacing, accessible high-contrast layout. Use abstract lines and placeholder blocks rather than legible personal data, no government emblem, no brand logo, no watermark.
