#' protomapr: Add Protomaps Layers to Leaflet Maps
#'
#' The protomapr package provides functions to add Protomaps vector tile
#' layers to leaflet maps in R. Unlike raster tile providers, Protomaps
#' offers full customization of colors and features, self-hosting from a
#' single PMTiles file, and smooth vector rendering at any zoom level.
#' See \code{vignette("getting-started")} for why you might choose Protomaps
#' over standard provider tiles.
