## Exact actual generation prompt

```text
Use case: product-mockup
Asset type: one complete custom Magic: The Gathering card face for Clash, P03.
Flat upright high-resolution digital card, approximately 5:7 portrait, full black rounded outside border visible.
Image 1 is FRAME/LAYOUT REFERENCE ONLY (growth-spiral-rna): match conventional modern M15 geometry, conventional gold with green and blue accents 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: Polyphemus kneels on a dark shore and raises one hand toward the sea; his wounded eye is covered. One pale line of surf answers him. 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. 
CARD DATA — print verbatim without field labels:
Name: Polyphemus's Prayer
Mana cost: {G}{U}. Render ordered proper Magic circular glyphs, never braces or the letters G/U: generic numerals, green tree and blue water drop as specified.

Rules (preserve all paragraph breaks):
Destroy target artifact or enchantment. If you lost life this turn, draw two cards.
No power/toughness badge or statistics.

Collector identifier: P03

No added flavor, reminder text, artist or official release credits. Exact punctuation, words, numerals and mana-symbol order. 
Do not omit any restriction, timing clause, or the words “may”, “target”, “up to”, “tapped”, “each”, “only”, “your”, or “Sacrifice” where present. No rules amendments. Keep full title, cost, type and set mark distinct; clear rules, stats and footer without overlap. No perspective, tabletop, sleeves, glare, or drop shadow.
```

## Exact actual correction prompt

```text
Use case: precise-object-edit. Image 1 is the edit target, Polyphemus's Prayer. Remove ONLY the pale Simic guild watermark behind the rules text, replacing it with the same quiet pale green-blue rules panel texture already around it. No watermark or logo inside rules panel. Preserve every other pixel as closely as possible: exact title Polyphemus's Prayer, G/U mana symbols, artwork, ordinary gold frame, Instant type, gold lightning set mark, bottom oval, P03 and CLASH • CUSTOM • PLAYTEST footer. Preserve EXACT rules text: Destroy target artifact or enchantment. If you lost life this turn, draw two cards. Preserve 5:7 portrait and entire black border. Do not add other text or art.
```

## Observed visual QA

Passed after one targeted built-in edit removed an unintended Simic guild watermark copied from reference. Entire revised image rechecked: correct title and G/U cost, Instant, exact destroy target artifact or enchantment and life-loss-this-turn draw-two clause. Gold green-blue frame, gold lightning, P03/footer, no stats. Wounded kneeling Polyphemus and raised hand remain coherent.

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.
