 * Single source of truth for the npm packages a Byline-on-TanStack-Start
 * install needs in the host application's `package.json`. Consumed by the
 * `deps` phase (to install missing entries) and by `doctor` (to report
 * what's missing without re-running the install).
 *
 * Versioning policy: all publishable `@byline/*` packages are released
 * in lockstep, so they share `BYLINE_VERSION` — including
 * `@byline/host-tanstack-start`, which previously rode its own `1.x`
 * line but is now part of the lockstep set from 2.x onwards.
 *
 * Scope: this list is intentionally minimal — only packages that are
 * directly imported by files we drop into the user's tree (`byline/`,
 * `src/routes/_byline/`, `src/ui/byline/`). Transitive deps reach the
 * user via the `@byline/*` package boundary and don't need declaring.
