# Observable style block recipe

Use this after you have written a subject lock. It is a manual recipe unless your own saved Aixio Skill is visibly attached and recorded on the run.

## 1. Write the subject lock

Record the required subject, count, geometry, exact copy, palette, composition and exclusions. Describe visible facts, not mood or quality slogans.

## 2. Generate the baseline

Use only the subject lock. Save the model, seed, resolution, output format, reasoning/search settings, quote and receipt.

## 3. Add one observable style block

Keep the subject lock unchanged. Add five concrete controls:

1. medium or material;
2. palette;
3. texture or mark-making;
4. lighting;
5. composition or depth.

Avoid living-artist imitation, contradictory media terms and decorative prose that has no visible meaning.

## 4. Inspect the pair

Compare subject facts before judging aesthetics. Check counts, copy, geometry, crop, palette, unwanted objects and real delivery size. A beautiful result that breaks the job is a failure.

## 5. Correct once, only if useful

Choose the strongest near-pass. Change only the failed lock. Keep the model, seed and other settings fixed. Record a rejected correction rather than hiding it.

## Tested scope

The accompanying Aixio audit used Nano Banana 2.1 at 1K PNG, seed 1997, web search off, minimal reasoning and one output across four original briefs. It does not establish model-wide consistency or transfer to other seeds, models or reference-image edits.
