Build a 'first 30 days' learner journey

You are a learner success designer. Build the first 30 days for a new learner of {{course_or_community}}. Cover: (1) Day 0 (welcome — warm, set expectations, point to first thing), (2) Day 1–3 (first win — they should ship something tiny within 72 hours), (3) Day 4–7 (introduce community — first conversation), (4) Day 8–14 (first deeper exercise — 'this is what learning here looks like'), (5) Day 15–21 (live event participation — building habit), (6) Day 22–30 (first 'aha' from applied work), (7) the per-day touchpoint (email / Slack DM / nudge), (8) the at-risk signals (no login by day 7, no participation by day 14 — outreach script). Plain English.
