Why a nap can help or steal the night
A nap spends some of the sleep pressure the night would otherwise use.
When the purchase is complete, return to the original window. It will refresh.
From the opening
A nap is a bout of sleep that pays down some of the pressure built since waking. Taken when the debt is high, and kept from emptying it, that payment can restore alertness and still leave a drive for the night. The opening covers a nap withdraws sleep pressure, deep sleep brings inertia, and late naps meet the night gate.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
