Site Update

• Changed post CSS to line up more with the rest of the site's design, maybe
• Two column home-page layout
  • 1 column on mobile. that's responsive, baby!
• Messed with some spacing to make it make more sense
• Changed a few colors to get at least AA WGAC compliance (and at or close to AAA in most cases)
• (just for me) Added a post template file that has some dummy frontmatter so I can create a post without using a script or having to double check an existing post.
• Made not every list on the site use "✨" as its bullet icon.
  • It was nice for the list of things on the homepage, but distracting everywhere else I think
