+#' Stamp the Civilytics logo onto a saved raster (PNG) image

+#' The raster analogue of [civilytics_logo()] for outputs that are already
+#' rendered to a file rather than held as a ggplot/grob — e.g. a `flextable`
+#' exported to PNG, or any `grDevices::png()` / `ragg::agg_png()` output.
+#' Resolves the *same* brand asset that [make_logo_grob()] uses, so file-based
+#' tables stay visually consistent with logo-branded plots, and composites it
+#' into a corner of the image. Pure base-graphics + grid + png — no new
+#' package dependencies.
+#'
+#' @param path Character. Path to the PNG to stamp. The file is overwritten
+#'   in place at its original pixel dimensions.
+#' @param type Character. `"wordmark"` (default) or `"mark"`. As in
+#'   [make_logo_grob()].
+#' @param variant Character. `"light"` (default, dark logo for light
+#'   backgrounds) or `"dark"` (reverse logo for dark backgrounds).
+#' @param position Character. Corner placement: `"bottom-right"` (default),
+#'   `"bottom-left"`, `"top-right"`, or `"top-left"`.
+#' @param width_frac Numeric. Logo width as a fraction of the image width
+#'   (default `0.15`). Height follows from the logo's aspect ratio.
