Domain settings [UI]

The per-Domain configuration modal — where a Director tunes how the expert authors: its generation direction, prose style, point of view, audio, and the AI model allocation behind it all. A tabbed DomainSettingsModal; Director-gated.

• Direction carries the AI allocation. AiProfiles / AiProfilePicker pick the active fleet profile (and optional per-category overrides); GenerationControls sets the generation knobs. This is the UI face of ai-model-routing — choosing a profile re-routes every category's model live.
• POV is a first-class mode. Single / Ensemble / Free (default) shape how prose narrates — a domain-level authoring stance, not a per-scene toggle.
• Style owns the fidelity axis. The extractive/framed/generative anti-hallucination posture lives here (one named axis), driving the grounding block folded into every scene call.
• Director-gated. These settings change how the expert speaks for everyone; only the Director may edit them (ACTION_META category edit, area governance).
