/**
 * Canonical JSON error response helpers.
 *
 * Two variants:
 *   jsonError       → flat:   { ok: false, error: string, code: string }
 *                    Used by cart routes, auth, and new code.
 *   jsonErrorNested → nested: { ok: false, error: { code, message } }
 *                    Used by confirm.ts — kept for client contract compatibility.
