Fix account page SIGSEGV: el_img extern signature mismatch

account.el declared el_img with 1 arg (attrs only) while the runtime

The arity mismatch caused the server to crash with signal 11 on every
request — TCP probe passed (bind was fine) but first HTTP hit segfaulted.

         Neuron is what I built in response to that. Not a startup in the traditional sense - no team, no funding, no press release - one person, nearly two years of work, and a conviction that this can be done differently. I wrote the memory architecture, I built the inference infrastructure, because the tools that existed weren&#39;t sufficient for what I was trying to build and so I built those too.

         Use it long enough and you&#39;ll understand why I couldn&#39;t have gotten there on top of existing infrastructure. Some things have to be built from the ground up to be built right.

         AI has genuine potential to free people to do work that actually matters to them - not to create engagement loops, not to harvest attention, but to actually serve the person sitting in front of it. That potential is almost entirely unrealized, not because the technology isn&#39;t capable, but because the incentives that shaped it were never oriented toward the person.
