Design a clean, professional single-page technical brochure/infographic in Persian (Farsi), right-to-left (RTL) layout. Title at the top: "نکات نصب و بهره‌برداری ترانسفورماتور جریان (CT)" with a subtitle below it. Include a simple, elegant technical diagram of a current transformer (CT) near the top: a horizontal primary line labeled P1 on the right and P2 on the left, with a coil/winding symbol on the line and two secondary leads labeled S1 and S2, plus a short caption below the diagram. Below the diagram, present exactly 4 numbered content blocks arranged in a 2×2 grid (or a vertical stack), each block containing: a bold circular or rounded-square number badge positioned on the RIGHT side of the block (since the layout reads right-to-left), a short bold heading next to it, a 1-2 sentence description below, and a small rounded tag/label. Use a distinct accent color for each of the 4 blocks (e.g., teal for block 1, amber/gold for block 2, blue for block 3, and red/coral for block 4 since it's a safety warning — make this 4th block visually stand out with a subtle red-tinted background and border). Overall style: modern engineering/industrial infographic, dark navy background with a lighter card surface, soft rounded corners, generous whitespace, subtle borders, clean sans-serif Persian font, minimal flat icons, high contrast and readability, vector-illustration quality, 4K, no clutter, professional utility-company branding look. Footer text centered at the bottom in small gray text.
