Core packages

    Routing, dev tooling, host templates, Rsbuild integration, and app shell primitives used across most Tamer apps.

    PackageRole
    tamer-dev-clientDev launcher (QR, HMR, recent servers, compatibility checks)
    tamer-hostLynx host templates — usually auto-installed by t4l create; add manually only for existing projects
    tamer-navigationNative stack transport (TamerNav push/pop/dispatch) — the foundation tamer-router builds on; use directly for custom coordinators
    tamer-routerFile-based routing, Stack/Tabs, system back hooks, cross-spoke state bridge
    tamer-pluginRsbuild plugin merging tamer.config
    tamer-app-shellAppBar, TabBar, Content, navigation chrome
    tamer-dev-appStandalone dev host app (Expo Go-style QR + HMR) — monorepo workspace, not an npm package

    t4l add-core installs everything needed for a production app: host templates, plugin, navigation, router, app-shell, screen, insets, system-ui, icons, transports, and env. t4l add-dev is a superset that also adds the dev launcher packages needed in an app (tamer-dev-client, tamer-linking).
