v3.22.0

Added

• Cloudflare Pages custom-domain deploy targets — configure a list of base domains in the Cloudflare Pages plugin settings (one per line, e.g. deepaste.ai), then pick one from a dropdown next to the project name in the deploy dialog to publish at <project>.<domain> instead of <project>.pages.dev. On deploy, Pneuma attaches the domain to the project and creates the proxied CNAME → <project>.pages.dev record (the Pages "add domain" API doesn't, so without it the domain would stay pending and never resolve). Requires an API token with Pages:Edit + the zone's DNS:Edit, with the zone in the same Cloudflare account; if the zone isn't found or a step fails, it falls back to pages.dev with a warning rather than returning a dead URL. The dropdown only appears when API credentials are configured (wrangler can't manage custom domains).
