// The Founder's Break - weekly reminder.
//
// Runs on a plain interval (the cron runner has no day-of-week syntax), works
// out the Eastern weekday itself, and only sends on Wednesday. Deterministic on
// purpose: no LLM anywhere in the send path. A kv marker keyed to the event date
// makes a double-fire a no-op, which is what lets the job run more than once a
// day without ever mailing the list twice.
//
// env: CORBEN_KEY, LIST_ID, FROM, NOTIFY
// event: { force: true } sends regardless of the day, for testing.
