Why glue alone is a poor hinge
Dried glue is a stiff film meant for a joint that stays still, so it cracks when asked to be the hinge.
When the purchase is complete, return to the original window. It will refresh.
From the opening
A hinge has to bend over and over while the parts it joins stay intact. Glue, once dry, is a relatively rigid film meant to stop two surfaces from moving, so used alone it becomes the piece that snaps. The opening covers glue films crack when bent, hinges need a flexing piece, and a thicker bead still cracks.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
