Physical constants.
These are all absolute constants. Environment parameters that in principle could change should go in scenario.f90.
To access a constant in a subroutine you should use camp_constants and then the constant value is accessed with const%pi or similar. Note that the type is called const_t (with a trailing _t) but the single saved variable to access them is just called const.
