slab: Aesthetic Code gets its own colours, and the seed catches up master
Aesthetic Code sessions were wearing Codex's palette. `profileName` mapped both onto the `-codex` family, so the one interface that IS Aesthetic Computer was the only one not painted in it. `-aesthetic` is that scheme instead — the prompt's own dark values, the same ones `render.mjs` paints the harness with, so a terminal running a piece and the piece itself finally agree about what purple is. The status grounds move inside the scheme rather than reaching for the usual green and amber: lifted while the machine works, pulled toward the prompt's pink when it wants you, settled deeper when it is done, drained when the session goes stale. A wall of terminals still reads at a glance, which is the only reason the families exist. The cursor is the prompt's block colour in every one of them — the mark that says which family a window belongs to even mid-scroll. It suffixes the palette, not the tool. The tool is still deciding what it is called and these names travel to other machines. `slab-aesthetic-profiles.swift` writes the seed rather than the live preferences, and that is not a preference: Terminal serves its profiles from memory and rewrites the whole domain when it saves, so sixteen profiles written under a running Terminal appeared to land and were gone by the next flush. The seed is the durable copy and the one other machines receive. The seed also went from 13 profiles to 89. Every `-codex`, `-msg` and `-loopboy` variant existed on this Mac and had never been captured, so a fresh machine has been getting a thinner set than the one it was modelled on.
