type View interface {
	// Exists checks if a view with the specified name exists.
	Exists(view string) bool
	// LoadViewsFrom registers a package view directory for template fallback.
	// Templates from registered directories are loaded after app views; if a
	// template name is already defined by an app view or an earlier package, it is skipped.
	LoadViewsFrom(path string)
	// LoadViewsFromFS registers an fs.FS (for example an embed.FS) as a package view source.
	// Templates are resolved relative to root within fsys; pass "." to use the whole filesystem.
	// Root may use either slash style ("views/admin" or `views\admin`) and leading "./" or "/"
	// are ignored. Filesystem sources are searched after app views and after directories
	// registered with LoadViewsFrom, in registration order.
	//
	// Unlike LoadViewsFrom, which accepts a directory that may only exist later, an fs.FS is
	// fixed at build time, so it panics if fsys is nil or root is not an existing directory
	// within fsys (including roots that escape it, such as "../views").
	//
	//	//go:embed views
	//	var views embed.FS

	RegisteredViews() []string
	// RegisteredViewFS returns all package view filesystems registered with LoadViewsFromFS,
	// in registration order. Each returned filesystem is already rooted at the root passed to
	// LoadViewsFromFS, so template paths are relative to it (for example "layouts/app.tmpl").

	// with the current view context. This shared data can be accessed by other parts of the application.
	Share(key string, value any)
	// Shared retrieves the value associated with the given key from the current view context's shared data.
	// If the key does not exist, it returns the optional default value (if provided).
