+"""Render a per-frontend test table from vitest JSON reports for a Gitea job summary (#136).
+
+Reads every *.json in the given directory (default: test-output), each written by an app's
+`test` target (reporters: json, outputFile: {workspaceRoot}/test-output/{projectName}.json), and
+prints a markdown table to stdout — one row per frontend app. The CI step redirects it into
+$GITHUB_STEP_SUMMARY. Stdlib only.
