Reframe 'Why TEE' headline

'Not a decentralized network' led with what we aren't, which sets
a defensive tone right when we want to claim the win. Replace with
'Speed of a backend, trust of a contract' — same conceptual move
(positioning the TEE-plus-chain model against legacy options) but
in positive language that names the actual value prop. Mirrored
in LandingHowItWorks and prototype 1.
