+// Emscripten-only: SDL 3.4+ ja no casa el GUID dels mandos de Chrome Android
+// amb gamecontrollerdb (el gamepad.id d'Android no porta Vendor/Product, el
+// parser extreu valors escombraries, el GUID resultant no està a la db i el
+// gamepad queda obert amb un mapping incorrecte). Com el W3C Gamepad API
+// garanteix el layout estàndard quan el navegador reporta mapping=="standard",
+// injectem un mapping SDL amb eixe layout per al GUID del joystick abans
+// d'obrir-lo com gamepad. Fora d'Emscripten és un no-op.
