So many images! 🖼️ Nice work wrangling all the changes

Blocking:

• condition referring to now-outdated FTL string
• rogue "Raffi headshot" text
• https://archive.is/kj2u7 is failing to load for me

Potentially blocking:

• The pink cloud images get quite large. Maybe they need another round of optimization or a different image format?
• I'm not sure how we want to handle single-language third party content on a multi-language page

LGTM r+ 🚢
