Minor fixes

[Bulmenisaurus]

• Find a new font, Rowdies perhaps? Edit: currently using Roboto Slab
• Update difficulty select screen containers as the text spacing is strange
• On load game, settings, and achievements, perhaps change back button to not overlap content?
• I have a strange offset on the play screen that is not often reproducible (perhaps reflow?)
• Make capitalization consistent across ui elements
• Building info: add spacing, maybe a dynamic grid
• Tech screen is broken on my pc
• On play screen top bar reveals the page background color. Either make corners not rounded (easy) or make the canvas dynamically resize (harder but probably better)
• There are doubled borders in the bottom bar.
• Buttons are super far apart on the bottom bar for some reason
• Move all inline css into style.css (this is probably a perpetual task)
• Move back button to top-left (or anywhere but bottom, this makes it look like the primary task in many pages)
• Potentially have an icon for the back button?
• Too much text in the difficulty screen
• Tutorial popup text should be Yes/No
• Music is 😶‍🌫️
• Disabled buttons should have an explanation
• Decide if we actually need save slots
• In shop screen stats (reputation + resources) need to be sticky so always visible
• Trade successful toast notification needs a background
• Check contrast of all text (maybe graphics too)
• Buttons on top and bottom bar need more spacing (10px is fine)
• Text in buttons needs to be vertically aligned (specifically in the bottom bar)
• Settings slider potentially need a more contrasting bg
• Only fade out text for disabled elements, not bg
• Achievements should be in two columns
• Add/remove html classes instead of setting inline css in js
• When tech screen button is flashing the width of the button changes, can lead to multiple lines when border is yellow and one line otherwise
• (Feature) incorporate text effects like blur, animations, bg (like landgreen does in his game)
• overhaul tech screen
• change building info button text from "help" to something else
• tutorial is uncompletable
