Why Phoenix isn't merging `config.exs` and `runtime.exs` configs?

Well, Know I’m embarrassed with such a dumb error…

On config.exs I correctly used config :lovelace, LovelaceWeb.Endpoint, however, on runtime.exs I wrongly set up as config :lovelace, Lovelace.Endpoint

Well sorry for this… I’m working on this project all day long, maybe it’s time to take a break haha

But all the research about compile time and runtime configs were so enlightening!
