Nailed it:
background:
linear-gradient(to bottom, #D5D0CC 0%, #40240F 10%, #40240F 15%, rgba(0,0,0,0) 17%),
linear-gradient(to right, #7E5831 0%, #B6AE80 55%, #CDCBA5 60%, #CDCBA5 70%, #DAD7B6 75%, #EBEACB 80%, #CACBA9 90%, #B4B18E);

Yup, I've cracked the code. Totally got it.
Time to crack the other case, in (cascading) style! LOL jk, I'm not writing all those linear gradients.
Edit: Okay, so I missed the iSoaker logo, big deal.
