/**
 * The legal pages' data, tested where a mistake would be invisible. PLAN.md §9, phase 6.
 *
 * ---------------------------------------------------------------------------------------
 * WHAT IS ACTUALLY AT RISK HERE
 * ---------------------------------------------------------------------------------------
 * A privacy policy is prose, and prose is not testable. What IS testable is the small set
 * of structural promises the page and the Play declaration both rest on, every one of
 * which fails silently:
 *
 *   - a row with no retention line renders a card with an empty "How long" — which reads
 *     as "we keep this forever" or "we keep nothing", depending on the reader;
 *   - an `app`-scoped row with no Play mapping means a question on the console form gets
 *     answered from memory, which is the exact failure D33 exists to prevent;
 *   - a row that claims the app shares something contradicts the premise the whole page
 *     rests on, and would be a real disclosure defect rather than a typo;
 *   - a data type that is not the console's own, which the form then never asks about;
 *   - the consent sentence and /terms stating different minimum ages, which is the kind of
 *     inconsistency a reviewer finds and a developer never does.
 *
 * None of that shows up in a build, a type check or a link check: the page renders
 * beautifully with an empty cell and a wrong number in it.
 *
 * The generated Play document is checked by `scripts/playDataSafety.mjs --check` rather
 * than here — a generator's output is a build artefact, and comparing it in two places
 * means fixing it in two places.
