A hands-on project to carry through

Reading only gets you so far. Build one small app alongside the pages:

"Order Notes Notifier" — an embedded app that lists recent orders (step 5), shows them in Polaris (step 6), listens to orders/create (step 7), adds a block to the storefront (step 8), and charges $9/month after a 7-day trial (step 9).

Each page has a Project step box telling you what to add.
