/**
 * DeploymentCommandCenter — a composed, app-controlled "deploy console" block
 * that wires four presentation-only developer-tools components together behind a
 * single small demo state machine: an EnvironmentSwitcher in the top bar, a
 * DeploymentPipeline as the main column, a LiveLogStream beneath it, and an
 * ApiRequestInspector in the side panel.
 *
 * IMPORTANT — DEMO ONLY. Nothing here talks to a real deployment provider. Every
 * repo, endpoint, id, header, and timing is fictional and provider-neutral
 * (repo `acme/ledger-web`, host `api.acme-deploy.dev`). Credential headers are
 * pre-masked placeholders (`Bearer ••••••`) and the inspector redacts them
 * anyway. The block only feeds the components a scripted request/response/log
 * timeline in response to its own controls — it is a copy-paste starting point
 * you rewire to your real backend.
 *
 * Determinism: no `Date.now()` / `Math.random()` / `new Date()` runs during
 * render, initializers, or module scope. Timestamps derive from a fixed
 * baseline; the run only advances inside timers/handlers. Clean-room original.
