Single activity_log table powering two views: chronological timeline
on each order detail page (replacing the old fulfilment card) and a
global feed at /admin/activity with tabs, category filters, search,
and pagination. Real-time via PubSub — new entries appear instantly,
nav badge updates across all admin pages.
Instrumented across all event points: Stripe webhooks, order notifier,
submission worker, fulfilment status worker, product sync worker, and
Oban exhausted-job telemetry. Contextual action buttons (retry
submission, retry sync, dismiss) with Oban unique constraints to
prevent double-enqueue. 90-day pruning via cron.

When a Stripe checkout session expires without payment, if the customer
entered their email, we record an AbandonedCart and schedule a single
plain-text recovery email (1h delay via Oban).
Privacy design:
- feature is off by default; shop owner opts in via admin settings
- only contacts customers who entered their email at Stripe checkout
- single email, never more (emailed_at timestamp gate)
- suppression list blocks repeat contact; one-click unsubscribe via
signed token (/unsubscribe/:token)
- records pruned after 30 days (nightly Oban cron)
- no tracking pixels, no redirected links, no HTML
Legal notes:
- custom_text added to Stripe session footer when recovery is on
- UK PECR soft opt-in; EU legitimate interests both satisfied by this design

Stripe.Checkout.Session is a struct that doesn't implement Access,
so get_in with atom keys fails. Use direct struct field access instead.
