 * Slack credentials and derived settings, resolved once when the route is
 * built and carried on the request context.
 *
 * Handlers read this instead of `env` directly so tests can construct a route
 * with explicit config. Mutating `process.env` per-test is not viable: Deno's
 * `--parallel` runs test files in workers that share one process environment,
 * so concurrent files clobber each other's settings.
