Develop a fresh and professional brand identity for OvaClean, a Nigerian cleaning service that focuses on reliable home, office, and shortlet cleaning. The branding should feel clean, trustworthy, and modern. Create a logo (icon + wordmark), define a simple color palette and typography style, and apply the identity across mockups such as staff uniforms, cleaning supplies, and a social media flyer or before-and-after post to show how the brand would appear in real use.
