What is a memory rotation?

A memory rotation is the curated pool of photos, videos, and messages a resurfacing app draws from — the deliberate shortlist, not the whole archive, cycling back into view over time.

Context

Rotation quality follows curation, not size: thirty meaningful photos outperform three thousand unsorted ones. The rotation is a playlist for your past; the archive stays the library.
