-- 0029_marketing_events — minimal funnel tracking for /migrate.
--
-- Records two event types:
--   migrate_view           — fired when /migrate/<source> renders
--   migrate_lead_submitted — fired when POST /v1/migration-leads succeeds
--
-- Source values: convex | supabase | firebase | mongodb | drizzle |
-- prisma | postgres | hasura | nextauth | other | hub (the /migrate
-- index page itself).
--
-- No PII; ip_hash optional for future dedup-by-visitor logic. Customer
-- emails are recorded only in migration_requests (the actual lead).
