  We develop a new setting in the framework of braneworld holography to
describe a pair of coupled and entangled uniformly accelerated universes. The
model consists of two branes embedded into AdS space capping off the UV and IR
regions, giving rise to a notion of dS wedge holography. Specializing in a
three-dimensional bulk, we show that dS JT gravity can emerge as an effective
braneworld theory, provided that fluctuations transverse to the brane are
included. We study the holographic entanglement entropy between the branes as
well as the holographic complexity within the `complexity=anything' proposal.
We reproduce a Page curve with respect to an observer collecting radiation on
the UV brane, as long as we take the limit where gravity decouples in that
universe, thus acting as a non-gravitating bath. The Page curve emerges due to
momentum-space (UV/IR) entanglement and can be understood as analogous to the
`confinement-deconfinement' transition in theories with a mass gap. Moreover,
the analysis of complexity shows that the hyperfast growth phenomenon is
displayed within a set of proposals, while late-time linear growth can be
recovered for a different set. Our framework thus provides new test grounds for
understanding quantum information concepts in dS space and dS holography.
