/**
 * Unit tests for the generalized account-deletion-request email helpers
 * (task 11).
 *
 * These are the pure, env-free helpers consumed by the
 * `misc.sendDeletionRequestEmail` tRPC mutation (re-exported from `misc.ts`).
 * Kept in a separate module so they can be exercised in `bun:test` without a
 * populated `.env` (which `~/env/server` requires at import time — un-runnable
 * in this worktree).
 *
 * Coverage:
 *  - `DELETION_PRODUCT_SCHEMA` accepts the two known products + rejects others.
 *  - `deletionCookieName` returns per-product distinct names; Lineage keeps
 *    the legacy `deletionRequestSent` for redirect backward-compat.
 *  - `deletionEmailContent` produces product-branded subject + operator +
 *    user HTML bodies; the requester email appears in the operator body and
 *    the account email appears in the user body; the 24h cancellation
 *    window instructions are present in the user body.
