      "prompt": "Use case: illustration-story\nAsset type: landscape conceptual editorial hero illustration for an English beginner Litecoin guide, horizontal 3:2.\nPrimary request: illustrate \"How to read a Litecoin price chart without mistaking a close for the whole story.\" Show an irregular hand-drawn line partially visible through two simple overlapping paper frames as a metaphor for different observation windows.\nScene/backdrop: warm cream textured paper with generous quiet areas.\nSubject: one expressive irregular navy ink line with a few rises and dips across the paper, partly covered by two modest handmade paper frames/cutouts in terracotta and offwhite. Each frame reveals a different fragment of the same line. The line should look like an artist's ink gesture, not a real financial chart, plotted axis or data series.\nStyle/medium: original gouache and ink editorial illustration with tactile cut-paper edges, uneven brush pigment and subtle handmade print texture. Calm, thoughtful visual composition rather than an infographic, UI or glossy 3D render.\nComposition/framing: landscape 3:2 with the two viewing windows and differing visible fragments readable at thumbnail scale, balanced shapes, comfortable margins; no extra objects.\nLighting/mood: softly lit tactile illustration, quiet clarity and curiosity.\nColor palette: deep navy, muted terracotta, warm cream and restrained warm gray.\nConstraints: absolutely no text, letters, numbers, labels, ticks, axis markings, actual prices, logos, watermark, candles, financial interface, fake data labels, QR codes, addresses or passwords. No coins, phones, clocks, globes, neon or glowing network lines. The illustration must not present invented market data as measured evidence. It is a conceptual image about observation windows; exact charts and data belong in separately drawn figures.\nAvoid: generic rising-profit arrow, stock-market promotional graphics, smooth gradient tech art, photographic desks or document-folder motifs.",
