+# Run a startup version check and return a banner UI element
+
+Call this **outside** `server()` – typically in `global.R` or at the top
+of `app.R` – and embed the returned value directly in your UI
+definition. Because the check runs at startup the banner is present on
+first render with no loading delay, and no `uiOutput()` / `renderUI()`
+wiring is needed.
+
+## Usage
+
+``` r
+check_app_version(
+  github_user,
+  github_repo,
+  app_version = NULL,
+  verbose = FALSE
+)
+```
+
+## Arguments
+
+- github_user:
+
+  GitHub username or organisation that owns the repository.
+
+- github_repo:
+
+  Repository name. Also used as the package name for
+  [`utils::packageVersion()`](https://rdrr.io/r/utils/packageDescription.html).
+
+- app_version:
+
+  Optional fallback version string for environments where the package is
+  not installed (e.g. shinyapps.io). Pass the result of your
+  `app_version()` function here. Ignored when
+  [`packageVersion()`](https://rdrr.io/r/utils/packageDescription.html)
+  succeeds.
+
+- verbose:
+
+  Logical; if `TRUE` a banner is always returned. Defaults to `FALSE`.
+
+## Value
+
+A
+[`shinyWidgets::alert()`](https://dreamrs.github.io/shinyWidgets/reference/bootstrap-utils.html)
+UI element, or `NULL` when there is nothing to show (up to date in
+non-verbose mode).
+
+## Details
+
+**Normal mode** (`verbose = FALSE`): returns a banner only when a newer
+version is available or when the check fails. Returns `NULL` when the
+app is up to date (Shiny silently ignores `NULL` in the UI).
+
+**Verbose / debug mode** (`verbose = TRUE`): always returns a banner –
+including a success banner when up to date – so you can confirm the
+check ran and inspect both version strings during development.
+
+## Examples
+
+``` r
+if (FALSE) { # \dontrun{
+# global.R or top of app.R
+source("version_check.R")
+version_banner <- check_app_version(
+  github_user = "my-org",
+  github_repo = "my-shiny-app",
+  app_version = app_version()   # fallback for shinyapps.io
+)
+
+# ui.R
+fluidPage(
+  version_banner,
+  # ... rest of UI
+)
+
+# Verbose mode for development
+version_banner <- check_app_version(
+  github_user = "my-org",
+  github_repo = "my-shiny-app",
+  app_version = app_version(),
+  verbose     = TRUE
+)
+} # }
+```

+# Resolve the current app version
+
+Tries two strategies in order:
+
+1.  `utils::packageVersion(package_name)` – works when the package is
+    installed locally (development, local
+    [`runApp()`](https://rdrr.io/pkg/shiny/man/runApp.html)).
+
+2.  `app_version` argument – an explicit version string supplied by the
+    caller, e.g. from an `app_version()` function bundled with the app.
+    Used on shinyapps.io where the package is not installed.
+
+## Usage
+
+``` r
+.resolve_app_version(package_name, app_version = NULL)
+```
+
+## Arguments
+
+- package_name:
+
+  Name of the package / repository.
+
+- app_version:
+
+  Optional fallback version string.
+
+## Value
+
+A character string with the version (e.g. "1.1.0"), or NULL if neither
+strategy succeeds.
