/**
 * Rule presets — the customer default vs the full `fragments` dogfood preset.
 *
 * Both are derived from the tier SSOT (`./tiers.ts`); neither re-lists rules.
 *
 *   - **customer default** — Tier A on (inert until a contract is authored),
 *     Tier B off, Fragments-internal rules excluded entirely. This is the
 *     vocabulary-first, no-flood default a customer repo gets.
 *   - **`fragments`** — every rule on, for Fragments' own internal scans.
 *
 * These produce the rule-config half of a `GovernanceConfig`. The hygiene
 * *policy facts* (e.g. `style.rawColors.forbid`, spacing scales) are a separate
 * config axis the customer default simply omits — so a Tier-B rule that gates on
 * a policy fact (raw-color/spacing/typography) stays inert regardless of its
 * config flag, and the customer default produces zero findings without a
 * contract.
