free public shelf // no paywall

free guides that actually do something

twelve free route seeds. not “lead magnets” in a fake beard — each one is a small working manual, build note, or orientation point. scan the shelf, pick a route, download the thing, then leave with a task.

best path: grab START HERE, then one route seed. don’t download twelve PDFs and call it progress. that’s just hoarding with better typography.
