    ` and `<main>` tags.. No `<!DOCTYPE>`, `<html>`, `<head>`, `<body>`, `<header>`, `<nav>`, or anything like that.. That"[bad string]
    Since I can"t include a `<head>`, I"m going to have to get creative with SEO.. I can"t output meta tags, title tags or anything like that (even though the prompt *implies* I should), so I"ll need to embed the necessary information directly into the visible page content, and include a canonical URL as part of the structure.. I am specifically going to focus on an effective H1 and internal linking..
    The visual style is clear: linear/Spotify.. Think dark mode, cool tones, clean and minimalist, with a large border-radius for the elements.. I"m aiming for a dark background (deep blue/purple) with a blue/purple gradient accent. I"ll need to define a good set of `:root` variables in the `<style>` section to handle all the colors, shadows, and borders consistently.. Sans-serif fonts are the way to go, likely Inter or a similar system font, for good readability..
    I"m structuring the `<main>` content with a hero section featuring a prominent H1, a brief intro, and possibly an image (`media/requirements-interface-1.jpg`). Following that, I"ll have a requirements grid for the main platforms: Windows, macOS, and Android.. Then, a more detailed table or list to specify CPU, RAM, and disk space.. I"[bad string]
    The H1 will be SEO-optimized, incorporating the brand and core theme: "FDM (Free Download Manager) 系统要求与运行环境指南".. I"ll update the page information as of January 20, 2026. I"ll include an internal link to `/download/` with an anchor text that contains "FDM"..
    I"m thinking of these `:root` CSS variables: `--primary`, `--accent`, `--bg-deep`, `--card-bg`, `--text-white`, `--text-gray`, `--border-radius`, and `--shadow`. I"ll use those to keep things consistent.. I"[bad string]

    **Generating Concise CSS**
