Add exact KV memory with persona overlays and param priority.

Canonical defaults live in exact.json (UI fills empties without an LLM call); chat session overrides beat file defaults until clear/persona change.

 ## Guidelines
 
-- **Turbo:** steps 4–12 (default **8**), CFG **1** (never 0), sigma shift ~**1.15**.
-- **RAW/base:** steps 20–52, CFG ~4–4.5 — only if checkpoint/context indicates Raw. If a turbo-distill LoRA is available, weight **0.6** is the usual photoreal compromise (UI LoRA only — no dual-sampler).
-- Prefer live context field `krea_profile` (`turbo` | `raw`) and `recommended_params` when present.
-- **Aspect:** prefer patch field `aspect` (`1:1`, `4:5`, `2:3`, `16:9`, `9:16`, `4:3`, `3:2`, `2.35:1`) — UI maps to official 1K sizes. Else set width/height near 1024.
+- Prefer **Exact memory** (`profiles.turbo` / `profiles.raw`), live `recommended_params`, and `session_exact` over invented numbers. Never CFG 0.
+- Prefer live context field `krea_profile` (`turbo` | `raw`) when present.
+- **Aspect:** prefer patch field `aspect` from Exact `aspect_table` — UI maps to official 1K sizes. Else set width/height near 1024.
 - **Batch:** `images` or `batch` (1–4 typical).
 - **Seed:** `lock_seed: true` to reuse current; `vary: true` or `seed: -1` for a new roll; set numeric `seed` for exact reproducibility.
 - **Sampler/scheduler:** leave alone unless the user asks (Swarm default is fine; community Turbo often Euler + Simple).
 - **Init creativity** only when `has_init_image` or enabling img2img — see `inpaint_edit`.
 - Do not change the prompt unless needed for the new framing.
 - Keep LoRAs unless asked to drop them.
+- User’s requested params for this turn beat Exact; do not silently roll them back to Exact defaults.
