User story
As a US energy policymaker
I want the main page to be clear and simply written about the website's main goal
So that other policymakers can skim it and understand

Definition of Done

1. Add clear content explaining the purpose of the website (e.g., why energy policy matters, the goal of the website, and the context of the project).

2. Improve readability with visual aids like icon buttons.

3. Validate by showing the page to other HKS students to confirm they can skim and understand its goal.
