studena

Could you please clarify what “studena” refers to in your request? It could denote different things—a place (such as a village or river) in a Slavic-speaking country, a surname, a brand, or a linguistic term meaning “cold” in some languages. If you provide the intended context or country, I can draft a precise, neutral, wiki-style article under 300 words. If you’d like, I can also prepare a brief disambiguation-style stub that outlines the most common possibilities.
