Based on the reference cover's composition, visual metaphor, and WeChat public-account thumbnail readability, generate a new horizontal WeChat public-account cover. Output size: 1456x582, aspect ratio about 2.5:1; the core subject and necessary title information should also work within WeChat's safe square crop. WeChat article title: {fill in the WeChat article title} Intro: {fill in the intro} Original cover method: What You Don't Know About LLM Training: Principles, Paths, and New Practices dual-skill style Create a horizontal WeChat public-account article cover, 2.35:1 aspect ratio, for an article titled "What You Don't Know About LLM Training: Principles, Paths, and New Practices". Central concept: visualize abstract tool capabilities as interface windows, code snippets, node networks, control consoles, AI workflows, or a glowing system core. Style: preserve the reference cover's visual direction: high-saturation poster/tech-advertising visuals. Use a palette inspired by #d87757 (orange), #dbc6c9 (cream), #794e5a (brown), #db7754 (orange). Keep the image editorial, conceptual, and readable as a small WeChat thumbnail. Composition: medium density, suitable for one main visual metaphor with a small amount of title text. Keep the main subject and any essential title text inside the safe square crop, while using the full wide frame for atmosphere, secondary symbols, or directional motion. Text strategy: use either no text or a very short headline fragment from the title. If text is used, make it large, clean, and integrated into the layout rather than pasted on top. Mood: match the article skill "What You Don't Know About LLM Training: Principles, Paths, and New Pr... dual-skill style" -- useful, sharp, high-signal, and slightly more memorable than a normal tutorial thumbnail. Avoid: photorealistic clutter unless the source cover is photo-led, fake logos, unreadable tiny text, generic gradient blobs, stock-office imagery, watermark-like marks, and literal screenshots unless the article is explicitly about software interfaces.
