Hi again! This is a follow-up, this time with a blank map of Russia. White means it's Russian territory, without disputes. Light grey means disputed (Crimea and South Kurils). Thin border means a possible future merger of federal subjects. In Yakutia, the thin border simply indicates all historical time zone boundaries since 1991. Light grey borders within federal subjects mean that that federal subject used to be 2+ separate federal subjects. Feel free to use it.
