A minimalist institutional logo for "Bio Rincão - Atlas do Pampa". Professional scientific project branding. Vector style, clean monoline design. The symbol is a sophisticated and elegant stylized DNA double helix where one strand organically transforms into a native leaf and a flowing river line, and the other strand represents geological stone textures. Clean geometry, academic and high-end. Palette colors: Deep forest green (#1B4332), petroleum blue (#1D3557), and a subtle earthy matte gold accent (#C2A15A). Solid white background. No realistic details, no cartoon
