Development record

.abcd/development/brief/04-surfaces/22-site.md:96-99 describes the remote stages' confirmation with no case for a site already live, and --replace-existing appears only in the flag appendix at .abcd/development/brief/04-surfaces/22-site.md:397. `site setup --help` says that flag publishes over a site the host already serves without asking, and that --yes without it refuses when such a site exists. commands/site.md:284 and docs/reference/cli/commands.md:5746 carry this; the chapter's prose does not.
