We need to parse the user's instruction carefully. The user says: "You are a specialist in product analysis. You will receive only the title of a product and must write a complete, natural, visually pleasing review, as if published in a blog or e-commerce professional. The text should be in pure HTML (without CSS), but can and must use formatting elements to make the content beautiful and easy to read, such as: well-spaced paragraphs (

), titles and subheadings (

,

), emphasis with and , organized lists (
    and
  • ), line breaks (
    ) where it makes sense. Generate inline CSS, but without using backgrounds and colors. Always align content to the left, never centered. Never use max-width nor width. The writing should be engaging and natural, not artificial. Structure the answer following this logic: Input: Title of product : Fones de Ouvido Intra-auriculares com Microfone - Compatíveis com Kindle Fire, Galaxy S8+, Note 8, Fire HD 8/10, Voyage, Oasis e Outros. Output expected: a text in HTML, spaced and well formatted, using lists and basic formatting to create a pleasant and fluid reading." Thus we need to output a review in HTML, without any external CSS, and also generate inline CSS (style attribute). The inline CSS should not include backgrounds and colors; presumably we can use font-size, line-height, margin, padding maybe border? Those are not backgrounds or colors; allowed CSS properties: font-size, line-height, margin, padding, border maybe? The instruction says "Generate CSS inline, though without using backgrounds and colors". So we can use style attribute with properties that are not backgrounds or colors. But can we use border? Yes. We must also not use width or max-width; also align content left is default. We should write a review for "Fones de Ouvido Intra-auriculares com Microfone - Compatíveis com Kindle Fire, Galaxy S8+, Note 8, Fire HD 8/10, Voyage, Oasis e Outros". This is a product review for in-ear headphones with a microphone, compatible with many devices (Kindle Fire tablets, Galaxy S8+, Note 8, Fire HD 8/10, Kindle Voyage, Kindle Oasis, and other devices). The review should be natural, engaging. Should follow structure: - Title (maybe

    ). - Introduction: what the product is, why it's interesting. - Build quality and design: materials, comfort, ergonomics. - Sound quality: bass, mids, highs, clarity, volume. - Microphone quality: voice clarity, noise reduction. - Compatibility: integration with listed devices, plug type (3.5mm), inline controls (maybe). - Inline controls: pause/play, volume, etc. - Durability: cable, connectors. - Pros and cons: bullet points. - Conclusion: recommendation, rating. - Possibly includes usage scenarios: commuting, sports, calls. - Possibly a rating section like stars using Unicode. The HTML must not use CSS except inline style attributes. We need to ensure we use

    for paragraphs,

    for major headings,

    for subheadings,
    • for lists, and for emphasis. We need to embed inline CSS for readability: e.g., style="line-height:1.6; font-size:16px; margin:0 0 12px 0;" for each

      . That's allowed. Or we can set style on elements like

      but keep it left-aligned. We cannot use "background" or "color". We can use "font-family", "font-size", "font-weight", "line-height", "margin", "padding", "border", "text-align" (left default). Actually, we can use "text-align" to explicitly set left; but left is default. Not needed. We must avoid CSS classes or
