+# Play's rule that actually bites: JPEG or 24-bit PNG **without alpha**, shorter side >= 320,
+# longer side <= 3840, and **longer side <= 2x the shorter side**. A phone at its native
+# 1080x2400 is 2.22:1 and is therefore REJECTED, which is why the phone path crops system
+# chrome (status + navigation bars) before clamping to 2:1. A tablet frame is already inside
+# the 2:1 cap on every profile the SDK ships, so its crop defaults to 0 and is opt-in.
