After following Trailhead instructions, I have been able to install an unmanaged package into Trailhead Playground and confirm that I can add a Lightning Web Component to a page (namely the Opportunity page).

However, after doing the exact same steps to install the same package (and promote) in my Developer Org: I cannot see the Lightning Web Component

Could you explain why?

Found the answer. At the bottom of the Components palette, there's link "Deploy your domain". After my own domain is deployed, it must ALSO be rolled out to users (the very action that I previously had missed).
