A clean, minimalist flat vector logo centered on a solid, clean off-white background. The central icon features a stylized, elegant silhouette of a graceful female angel figure wearing a long flowing dress, with sweeping, stylized feathered wings extending outward on both sides. The entire graphic is rendered in a solid, muted slate-green or teal-gray color. The design features crisp, clean lines strictly in a two-dimensional format, with absolutely no drop shadows, gradients, 3D effects, or background textures. This is a high-quality, scalable vector graphic for professional branding. Aspect Ratio 1:1.
