Design a disruptive logo for 'HeartCast,' a podcast by Heart Mortgage focused on real estate, finance, and lifestyle. The logo should break away from conventional heart imagery and instead use abstract, modern elements that hint at connection, sound, and communication--such as geometric shapes, sound waves, or stylized podcast icons. The design should be bold and unique, with a clean font that stands out. Utilize a dynamic color palette that conveys energy and innovation, such as contrasting shades of blue and orange, to create an impactful and memorable logo.
