Refactoring Improvements

[timwekkenbc]

• Fixed how layout is handled so that it can handle both rule pages and list pages without janky css
• Removed unused CSS, Added CSS vars for commonly used values such as breakpoints and colors, Switched to using rem instead of px for padding to make more accessible
• Smoothed out how the page loads in
• Reduced load called when getting title for a page so it is more performant

Really like the move to the root css variables, especially for the rule state colours and breakpoints! Makes cohesive design so straightforward.

Thank you for all the work you put into refactoring this! It looks so good!
