save-as-standalone-html

Bundle the artifact into a single self-contained HTML file.

How

• Inline all <style> and <script>
• Convert <img> and @font-face to data: URIs (small assets) OR upload large assets as public artifacts and reference by stable URL
• Strip dev-only build artifacts (sourcemaps, hot-reload hooks)

Constraints

• Single .html file
• File size budget: ≤ 5 MB unless user accepts more
• Keep <title>, <meta charset>, and viewport meta intact

Verification

• Save the file, disconnect network, double-click → renders identically
• No console errors about missing resources
