Notes

• I didn't go so far as to make the charts fully responsive due to time constraints - mobile users will be able to download nice-looking bar, stacked, and waffle charts, but they'll need to scroll left-right to see the full bar/stacked charts. Waffle charts are stacked.
• Breadcrumbs are hidden on very small screens as they would take up a lot of vertical reestate.
• @TaiWilkin I was able to do half of 043 and changed the color of the notification, but couldn't find where the time was set.
• Set a max-width for elements that were identified in 042.
• Updated text according to 044, 049, 051, 052, 053, 054, & 055.

Testing Instructions

• git pull
• View all pages of app and ensure that it looks ok on smaller screens.
• Updated text according to 044, 049, 051, 052, 053, 054, & 055. Please check my work 😬 I think I got everything!

Taking a look now. Thanks for your quick turnaround on that client feedback!

@TaiWilkin Great, thanks for the review! This should be ready for another look. I did a couple other little things while I was in there to make the app a bit faster / more accessible.
