Restructure vague resources section into focused homepage sections

[andrewmcodes]

Summary

Some homepage sections are too abstract and could be more actionable.

Problem

• Generic labels like "Resources" do not clearly tell visitors what they will find or why it matters

Proposed changes

• Replace or split broad sections into clearer areas such as:
  • Projects
  • Writing
  • Podcast
  • Uses
  • Speaking

Acceptance criteria

• Each section has a clear purpose
• Each section contains concise descriptions and useful links
• Homepage scannability improves
