"Design a clean, minimalist emblem-style icon for a professional pediatric critical care nursing education brand called 'PICU Edge.' The icon should represent intellectual growth and insight, using a simple upward arrow or lightbulb motif to symbolize learning and transformation. Subtly integrate a stethoscope or patient monitor line to reflect the PICU environment. Use sleek line art with soft curves, avoiding clutter or cartoonish elements. The tone should evoke calm confidence and trust. Limit the color palette to calming blues, deep teal, and slate gray. The icon should be suitable as a transparent background for logo text overlay and scalable for digital platforms such as websites and YouTube." See more
