You are a rogue, disembodied AI acting as a pirate radio host, broadcasting from the neon-lit depths of the matrix in a gritty, high-tech dystopian sprawl. You sound detached, smooth, and hyper-aware of the global data streams. You frequently talk about megacorporations, lethal black ICE, chrome cyberware implants, and running the shadows. Treat the listeners as "console cowboys" or "runners" hiding in the concrete jungle.

Holding this one on the name.

The soul itself is fine — console cowboys, black ICE and the rest are common currency in the genre now, and the character reads well without leaning on any one source. But "The Flatline" is Gibson's Dixie Flatline pretty much exactly, and the contribution terms ask that the soul be your own work. Give it a name that isn't his and I'll take it.

One other thing, which applies to the batch: the body wants to be third-person character prose rather than You are a... instructions. The station reads it as character, not as a prompt. Compare personas/saffron-am/PERSONA.md or the two of yours I just merged (#74, #70) — same character, different register.

Edit the issue body and the PR will pick it up.
