胶片颗粒纹理叠加层

Create a dark section wrapper with an animated film-grain texture overlay and vignette. The base background should be near-black. Overlay a semi-transparent noise texture using an SVG filter or CSS noise background that animates subtly (e.g., changing opacity or background-position) to feel like film grain. Add a radial vignette that darkens the edges. Center a short headline and paragraph inside. Typography should be a clean sans-serif in off-white with low opacity for body text. Use Tailwind CSS. The grain should be subtle—about 4-6% opacity—so it adds texture without reducing readability.

创建一个带有动画胶片颗粒纹理叠加和暗角的深色区域包装器。基础背景应为近黑色。使用 SVG 滤镜或 CSS 噪点背景叠加半透明噪点纹理，并添加微妙动画（如改变透明度或背景位置）以产生胶片颗粒感。添加径向暗角使边缘变暗。在中心放置短标题和段落。排版使用干净的米白色无衬线字体，正文透明度较低。使用 Tailwind CSS。颗粒感应微妙——约 4-6% 透明度——以增加纹理感而不降低可读性。
