viitamaks

I’m ready to write a concise, neutral wiki-style article, but I need a bit more context. The term “viitamaks” does not correspond to a widely known topic in my references. Could you clarify:

- What language or domain is this term from (e.g., Estonian, biology, a brand name, a fictional concept)?

- Is viitamaks a real subject, a product, an organization, a process, or something else?

- If you have a preferred scope (etymology, history, uses, safety/impact, notable research), please specify.

With that context, I’ll draft a concise article under 300 words.
