/*
<MODULE_CONTRACT>
<purpose>
[RFC-1198] Client-safe referral pattern constants — regexes and bounds shared
by the browser prefill (?ref), the worker redirect, and the partner schema.
Zero dependencies: importing this module must never pull the Zod schemas or
the reserved-slug table into a client bundle.
</purpose>
<non-goals>
  <item>No Zod, no loaders, no RESERVED_REFERRAL_SLUGS — those live in partners.ts (server-side).</item>
</non-goals>
</MODULE_CONTRACT>
<CHANGE_SUMMARY>
  <item>RFC-1198 fo-fix: extracted from partners.ts — the Zod module pulled RESERVED_REFERRAL_SLUGS ("sitemap") into the send-message client chunk and tripped dist.asset-integrity.validate's js-literal scan (DIST-ASSET-01).</item>
  <item>RFC-1257: structured CtaTarget + scenario-plumbed contact links</item>
</CHANGE_SUMMARY>
