Bug Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Expected

The first unique page content under https://squiggleconf.com/2024/sessions says:

SquiggleConf 2024 consisted of two days:

• Thursday, October 3rd: A full-day single-track series of full-length and lightning talks
• Friday, October 4th: Free 1-2 hour morning workshops
  See speaker details on Speakers.

The list should be left-aligned, as having list circles to the left of centered content looks weird.

Actual

The list is center-aligned:
