// Command terraform-provider-cairnobs is Cairn OBS's Terraform provider --
// PROJECT-SPEC.md names it a first-class deliverable alongside cairnobsctl
// ("CLI and Terraform provider are first-class, not afterthoughts"),
// but this is the first phase to actually build any of it.
//
// Scoped deliberately narrow to start: one resource
// (internal/provider.dashboardResource, cairnobs_dashboard), reusing the
// exact same JSON contract cli/cmd/cairnobsctl's "apply" subcommand and
// web's dashboard export button already use against
// api/dashboards.Handler -- "one JSON contract, multiple callers" is a
// design decision made back in Phase 3 (see cli/README.md), this
// provider is just a third caller of it, not a new contract. Alert
// rules, notification targets, and tenant/RBAC resources are real,
// disclosed future work, not attempted in this pass -- see README.md.
