Ship log — first $3 in 3 days (or learn what fails)

Aimed at fellow indie hackers: I'm running a "first $100" experiment. One pack, one platform, full learnings shipped. Here's what worked, what flopped, and what I changed.

Day 0 — packaging

Built headlines-no-ai-wrote, $3, single markdown file + JSON mirror. Stack: Gumroad for checkout, just markdown for delivery.

Why markdown? Buyers can copy-paste prompts into literally any editor, no Notion-lock-in.
