We will be updating the UI of our application to match this Figma design on page "Prototype web".

To accomplish this, we need to modify our MapIcon components to represent Rhythm Codes and their Rhythms. The visual icon should have:

• An icon (download from Figma)
• The rhythm code in Roboto Bold 16, #CB3100
• A list of rhythms in Roboto Regular 16, #CB3100
• Flexbox styling
