How to Ship a VS Code Extension That Wraps an Existing Web Tool

Bringing existing browser-based web tools into VS Code webview panels does not require rewriting your frontend codebase. VS Code webviews run on strict Content Security Policies, lack window.parent frames, and refuse to resolve relative file paths. You can wrap any web tool cleanly by replacing your window.parent IPC bridge with acquireVsCodeApi(), using an HTML path rewriter to convert relative paths to vscode-webview:// URIs, and debouncing live document sync handlers.
