The binary, its paths, environment variables, journal tag and URLs, the Makefile and the Debian package all take it from there, and a test fails on any other copy outside prose and `go.mod`.  The package grants `/usr/bin/www` one capability, `cap_net_bind_service`, so it can bind port 80 while running as the user. `getcap /usr/bin/www` shows it. With it www serves on port 80 and URLs carry no port; without it, as after `make install`, the port is 8080. www also takes port 80 where the machine lets every user bind low ports.
