/**
 * TASK-0124 — the database-AI client's pure display helper renders a
 * stored per-type record value for the mapping/preview/sample tables
 * (text/number/checkbox/select/date/unknown). The SSE streamers need a
 * fetch + auth store (covered by the integration + e2e suites); this file
 * covers the pure part.
 *
 * @vitest-environment node (no DOM needed; the config default is jsdom,
 * which is not installed — every web test opts into node explicitly).
