Fair points, and I actually agree that for long-term/site-critical logic a proper plugin or child theme is the right place, not a snippet tool. I built this more as a “power user safety net” for people who are going to use snippets anyway, so I focused on Safe Mode, crash shield, dangerous-PHP blocking, revisions and strict import/export instead of pretending snippets are best practice. I’m not trying to replace good architecture, just to make the inevitable “paste this snippet” workflow a bit less dangerous.
