+# Generates the Google Play store graphics from the app's own icon vectors.
+#
+#   ./tools/make-store-assets.sh [output-dir]        # default: ./store-assets
+#
+# Produces, matching Play's asset specs:
+#   icon-512.png                  512 x 512   32-bit PNG *with* alpha (ours is full-bleed,
+#                                               so every pixel ends up opaque anyway)
+#   feature-graphic-1024x500.png  1024 x 500  24-bit PNG, no alpha
+#
+# Output lands in ./store-assets/ *inside* the repo, never in $HOME: the editable sources are
+# the SVGs in tools/store-assets/ and these PNGs are the files that get uploaded to the Play
+# Console, so they belong with the release they were made for. Pass a directory to override.
