adding decimal place to breakpoints/ranges in both _globals.scss and _settings.scss as '.063' ends up leaving a tailing .008 in the calculation, and Chrome rounds up (meaning the 641 med range won't kick in until 642, large won't kick in until 1026, etc; this creates some really messed up displays right at the breakpoints as of right now
