You paste a Bash one-liner into Apple Notes for safekeeping. An hour later you copy it back, paste into Terminal, hit Enter, and bash blows up: command not found: 'curl'. The reason: Apple Notes silently turned your straight quotes …
For internet-facing domains, Let’s Encrypt is the right answer. But the moment you have a homelab service running on a .local domain, on a private subnet, or behind Tailscale — Let’s Encrypt either doesn’t work (HTTP-01 needs public reachability) or …
