## Exact actual generation prompt

```text
Use case: product-mockup
Asset type: one complete custom Magic: The Gathering card face for Clash, P08.
Flat upright high-resolution digital card, approximately 5:7 portrait, full black rounded outside border visible.
Image 1 is FRAME/LAYOUT REFERENCE ONLY (wayward-swordtooth-rix): match conventional modern M15 geometry, conventional monogreen frame. Use ordinary straight title bar, NO legendary crown. NO Nyx stars (not an enchantment creature). Replace every reference card datum, art, rules, set identity and credits. Image 2 is approved Clash support card P01: SET CONSISTENCY REFERENCE ONLY, painterly fantasy realism, type/rules typography and small lightning-bolt set mark; do not copy its art, card data, or green color where inapplicable.
Art only in the landscape art window: One bronze-hoofed hippocamp surges through clear turquoise water; a gold mane and the curve of its fish tail define the silhouette. Empty sea behind it. Painterly fantasy realism, one clear narrative focal moment. The source's deliberate simple composition matters: no additional crowds, armies, architecture, particles, or needless detail. No text inside art.
Use Beleren-style title/type and Plantin-style rules serif. Pale quiet rules panel; literal left-aligned rules with natural line wrapping, enough room for all words.

## Exact actual correction prompt

```text
Use case: precise-object-edit. Image 1 is the edit target Poseidon's Hippocamps. Change ONLY the color of the small lightning-bolt set symbol at right of the type line from orange-red to metallic GOLD, because this card is rare, not mythic. Keep the bolt's exact outline and placement. Preserve all other image content and lettering: title Poseidon's Hippocamps, cost 1 and green tree, Creature — Horse Fish, both complete rules paragraphs including the only once each turn limitation, 2/3 badge, P08 and CLASH • CUSTOM • PLAYTEST footer, all card frame and hippocamp artwork. No other changes.
```

## Observed visual QA

Passed after one targeted built-in edit corrected the rarity bolt from orange-red to metallic gold. Rechecked entire edited card: title, 1/G, Creature — Horse Fish, additional land on each of your turns, land you control enters during combat, draw two and only once each turn all correct. 2/3 badge, ordinary green frame, P08/footer and oval preserved. Clear horse forequarters, two bronze hooves and curved fish tail; title uses typographic apostrophe.

Reviewed actual generated pixels, including each rule line and symbolic glyphs; no unresolved game-data or layout defects. Modest typographic apostrophe styling and sub-percent aspect-ratio variance are cosmetic.
