Pagination keeps large lists fast and usable. APIs and dashboards use it to avoid loading every record at once.
ELI5
Think of Pagination as a labeled box where an app keeps important things. Splitting a long list into smaller pages or batches.
In practice
Use it when a feature reads, writes, migrates, validates, or audits stored information. In practice, define the owner, input, output, and failure mode before you rely on it.
