This isn't an argument for ripping everything out.
Most teams assume the only fix for a rigid CMS is a twelve-month replatform, so they live with the cost instead. That's a false choice. A handful of fast, standalone pages alongside your current stack can take the pressure off the queue without touching the platform underneath.
Zenlio Studio builds those pages in clean HTML you own outright, shipped in days, no developer ticket required. If a bigger move makes sense, we'll say so. If it doesn't, we'll say that too. Read the longer version in escaping CMS lock-in without burning a year, or start a conversation.
