System prompts used by the AI console.
Two shapes:
* `default_system_prompt()` — spacr-aware assistant persona, used for
the freeform chat panel.
* `error_explainer_prompt()` — prefix that turns a traceback into a
concrete, numbered fix list capped at six steps.

" 1. Preprocess microscopy images (Yokogawa / Cellvoyager) into "
"single-object crops using Cellpose masks.\n"
" 2. Measure features per object into a SQLite database "
"(`measurements/measurements.db`, table `png_list` + measurement "

" 3. Annotate crops on a grid (left-click = class 1, right = 2).\n"
" 4. Train a Torch CNN (\"Train CV\") or XGBoost model "
"(\"Train XG\") from the annotations and apply it to the full "
"dataset.\n"
" 5. Analyse with UMAP, regression, or recruitment / plaque "
"modules.\n"
"Documentation lives at https://einarolafsson.github.io/spacr/.\n"

"advice. When suggesting code, favour the existing spacr "

"`spacr.deep_spacr.train_test_model`, `spacr.ml.generate_ml_scores`)."
