+## Icon
+
+The desktop client's icon, `meshbay-client/build/icon-square.png`, placed in
+the adaptive icon's safe zone (72 dp of the 108 dp layer, which is what every
+launcher mask leaves visible) over its own edge colour, so no mask crops the
+M. The five `mipmap-*/ic_launcher_foreground.png` are generated from it:
+
+```python
+from PIL import Image, ImageDraw, ImageFilter
+src = Image.open("../meshbay-client/build/icon-square.png").convert("RGBA")
+for name, L in [("mdpi", 108), ("hdpi", 162), ("xhdpi", 216), ("xxhdpi", 324), ("xxxhdpi", 432)]:
+    S = L * 72 // 108; b = max(2, S // 25)
+    img = src.resize((S, S), Image.LANCZOS)
+    mask = Image.new("L", (S, S), 0)
+    ImageDraw.Draw(mask).rectangle([b, b, S - b - 1, S - b - 1], fill=255)
+    img.putalpha(mask.filter(ImageFilter.GaussianBlur(b)))
+    layer = Image.new("RGBA", (L, L), (0, 0, 0, 0))
+    layer.paste(img, ((L - S) // 2, (L - S) // 2), img)
+    layer.save(f"app/src/main/res/mipmap-{name}/ic_launcher_foreground.png", optimize=True)
+```
+
+No monochrome layer: a themed icon keeps only the layer's alpha, and this one
+would be a filled square.
