The Delete… review asks, for prompts in a saved pair, Archive (checked
on every open, D152's review) or Delete permanently, with their saved
pairs, in a D90 radio row. The choice rewrites the grid, sentences, title
and primary in place (openReviewDialog setRows/setPrimary), and the body
carries the chosen ids with their review digests. On the archived shelf,
Show archived prompts now reads the concept's way back, "← Prompt
library", as a plain button. TESTING.md records D154.
