Metro Solntsevo, the district's central park/pond (Bogdanova St),
Meshchersky forest park, the Levenson dacha (a Shekhtel-designed 1900
Art Nouveau landmark), and the Peredelkino writers' village — all
researched with real coordinates/history, in RU/EN x short/medium/long.
Verified against the live nearby endpoint: all 5 are found from the
user's actual coordinates (55.662303, 37.425486), radius expanding to
5100m to cover the farthest (Peredelkino village, ~5012m out).
