As a logged-out reader in Treatment, I see images on mobile web defaulted to full-width.
As the RG team, I can track metrics (e.g., logged-out reader 21d retention, spec to come) across Control & Treatment.

See mock/prototype (just the wide images portion): https://justinscherer.github.io/minerva-prototypes/closed%20sections%20links/index.html

• Change default image width configuration to match the device screen width responsively
• Experiment created
• Metrics instrumented
