+// Skald connector entry point.
+//
+// The MCP server itself is the upstream `@playwright/mcp` package, pinned in
+// package.json and installed by Skald beside this file (`npm ci --omit=dev`,
+// falling back to `npm install --omit=dev`).
+//
+// This file exists because Skald launches a `mcp_local` connector as
+// `<command> <mcp_config.args[0]>`, where args[0] is rewritten to the absolute
+// path of a *shipped* file — so `npx @playwright/mcp` cannot be expressed:
+// args[0] would be taken as the entry file's name.
+//
+// The wrapper rewrites argv with the flags the server needs in a display-less
+// container (headless, isolated in-memory profile, no sandbox) and then
+// imports the package's CLI module, which self-executes at import time.
+// cli.js is not listed in the package's "exports" map, so it is resolved
+// from the exported package.json path instead of a package subpath import.
