Improve design

[mbuffa]

General design

• Rethink the whole design
  • Experiment with a static side bar containing contact infos
  • Experiment with "less aggressive" color palettes
• Rethink the dark design. Moving stars are too distracting
• Make sure the mobile UI looks good

Improve styling on Article templates

• Table of content doesn't look great, and there should be a clear separation between it and the main body of text

Update static content

• Add a Hire Me page
• All WASM demos are broken. Remove them temporarily and find out what happened (was there a change in browsers' internal APIs?)
