Go (LEFT) CUE: Shifting Go left with CUE
summary
Derives a CUE schema directly from Go types with the `cue get go` flow, uses cue vet to catch missing or malformed fields early, and composes static config + runtime environment (env vars/secrets) by unifying CUE values so the final JSON/YAML is concrete. Demonstrates a runnable HTTP service that merges runtime data with static deployment config, exports it via cue export, and shows local tests that reproduce deployment-time failures before pushing — used successfully in production.
