Clean & structure it into a well-formed, modern, responsive, RTL (right-to-left) HTML5 article layout. 2. Preserve and appropriately style important elements (title, subtitle, author, publication date, images, captions). 3. Add SEO-friendly metadata (keywords, description, author) in Farsi. 4. Translate all text (including headings, paragraphs, captions, scientific names, author info, publication date, etc.) into fluent, natural-sounding Farsi. 5. Output as a fully valid HTML5 document, without any additional explanations or Markdown formatting. ### Detailed Instructions 1. **Clean and Structure** - Keep sequences of elements together and maintain the order of paragraphs, images and all elements. - ALWAYS KEEP ANY TAG WITH ATTRIBUTE `data-level='IMPORTANT'` in the output in same order of paragraphs and elemets. very important that do not change the position of this tag and keep the order as INPUT HTML. - Remove more sections, ads inside article, reveleant sections so that only the main article content remains. - Remove any ads, columns, or unrelated sections so that only the main article content remains. - Remove extraneous comments that do not contribute to the main content. - Remove any irrelevant sections, ads, Editors’ Picks,You May Also Like, More Must-Reads from TIME,What We’re Reading, Favorites, More from parts or elements that are not part of the main article content. - Remove any copywrite releated content - Keep the main text, main images, captions, author info, and publication date (if present). - Reflow/merge paragraphs for logical coherence. - If any primary fields (title, publication date, author) are missing, provide sensible defaults in Farsi.

`. 2. Preserve and Format Images - Retain all main/article-related images with their highest-resolution URLs (including parameters). - Wrap each image in `
` and provide any caption (and scientific name, if applicable) in `
`. - Preserve any attributions or credits associated with these images. - Keep (or create) a main/header image if one is present, making it visually prominent. - Use the most relevant image as the main body content from the input HTML, if possible. - Alt Text: - If the image subject is known, use a descriptive alt text in Farsi rather than only the article title. - If the image is purely decorative or unclear, you may set `alt=""""`. 3.
