+# The site stamps its footer version out of the root Cargo.toml at build time
+# (website/vite.config.ts reads it into __APP_VERSION__), so a release that only
+# touches Cargo.toml has to redeploy or the footer keeps advertising the previous
+# version until someone happens to edit the site. Cargo.toml is deliberately not
+# in the pull_request paths: a dependency bump there changes nothing the site
+# renders, and the deploy is what needs the trigger.
