Review snapshots in Chromatic

• Pages: 15/18 covered. Included by default.
• Posts: 7/103 covered. Excluded by default (posts share a layout).

Route breakdown

• Pages excluded:
  • /quotes: ~28M-pixel desktop snapshot is over Chromatic's 25M cap
  • /submitted: post-form state

  • /action
  • /australia
  • /funding
  • /if-anyone-builds-it-campaign
  • /join
  • /learn

Not exercised

• Pages that fetch from external APIs render against pinned fixtures, not live data.
• Cross-origin iframes and API calls (Tally, Luma, Mapbox, analytics, newly added widgets) are aborted at the browser boundary. Containers render as empty. Check the Netlify preview deploy to verify their real rendering.
• Only en locale is built.

tests/visual/README.md explains the annotation syntax and the coverage model.
