+"""Downsizes res/app_icon_50x50_64_color.png into watch/resources/app_icon.png.
+
+Pebble's own build tooling (process_sdk_resources.py) hard-fails any
+"menuIcon": true resource larger than 25x25px - the fixed size Pebble OS
+renders app icons at in the watch's own app launcher list (and, synced
+from the watch, in the mobile app's installed-apps list too). The source
+art in res/ is 50x50 (square, so it downsamples to exactly 25x25 with no
+letterboxing) - the color variant is used, per the same "prefer color"
+choice as the rest of this app's card art, over the companion
+*_gray.png fallback also present in res/.
+
+Generated output, like i18n_tables.auto.c and resources/img/*.png - not
+committed (see .gitignore), regenerate by running this script directly
+or via `pebble build` (wired into wscript alongside gen_card_images.py).
+Requires Pillow (`pip install Pillow`), not part of this repo's own
+desktop build/test toolchain.
