 - [Phase 11.2]: 11.2-01: Copy button falls back to a hidden textarea + execCommand when the Clipboard API is missing; a failed copy leaves the label unchanged
 - [Phase 11.2]: 11.2-02: D-42 resolved as defer-tag; no v0.1.0 tag in summercms.go, release path proven on a scratch clone with a local tag, and creating + pushing v0.1.0 and pushing master is a DEPLOY.md launch step
 - [Phase 11.2]: 11.2-02: the terminal check's clone override clones into the page's directory (git clone <override> summercms) so the page's cd summercms works with a local path
+- [Phase 11.2]: 11.2-03: the gate's --built stage builds in release mode only when the framework checkout build.sh uses has v0.1.0, else a dev build
