Only what main deploys is supported: the site on GitHub Pages and the container image tagged latest. Fixes land on
main and deploy from there.
Please report vulnerabilities privately, through GitHub's private vulnerability reporting: report a vulnerability (Security, Advisories, Report a vulnerability). Please don't open a public issue. You'll get an answer within a week, and the fix and advisory are published together.
In scope: the app's code and its handling of the data it fetches, the container image, and the workflows. The map and imagery services it reads from are their providers' own.
