/**
 * Canonical punimtag DEV targets — single source of truth for fixtures,
 * playwright.config.ts, and the Gitea Actions `e2e` job defaults.
 *
 * Values live in env-defaults.json so CI bash can read them without
 * compiling TypeScript (see `.gitea/workflows/ci.yml`).
 *
 * env-defaults.json ships placeholder host values (this is a public repo).
 * Real targets come from env vars (PLAYKIT_BASE_URL / PLAYKIT_API_BASE_URL —
 * set as Gitea Actions secrets in CI) or from a gitignored
 * `env-defaults.local.json` next to this file for local runs.
