1/**
2 * Canonical era taxonomy shared by the export pipeline, tests, analytics, and
3 * frontend. Each previously held its own copy of this list.
4 *
5 * These 8 values are the eras the published archive actually uses: every
6 * record in archive_records-public.csv carries one of them, the export
7 * pipeline (data/export-archive-data.js) emits them as `facets.eras`, and
8 * data/SCHEMA.md documents the same list. The order here is the published
9 * order of `facets.eras`; keep it stable.
10 *
11 * Note: issue #197 proposed a different 8-era taxonomy (a non-overlapping
12 * timeline with COVID-19 / Post-Trump / Second Trump splits). That proposal
13 * was not adopted. Joe decided issue #201 on 2026-07-09: use the canonical
14 * 8-era taxonomy below across the repository.
