+ * File-input path resolution for Electron 41.
+ *
+ * `File.path` was removed in Electron 32, so a plain `<input type="file">`
+ * picker can no longer read the chosen file's absolute path directly. The
+ * replacement is `webUtils.getPathForFile(file)`, exposed to renderers as
+ * `window.electronAPI.getFilePath` (by src/preload.js in preload-loaded
+ * windows, and by the fallback shim in src/renderer.js for the main window,
+ * which does not load the preload script).
+ *
+ * @module utils/file-path

+/**
+ * Resolve a File object chosen via `<input type="file">` to its absolute path.
+ * Falls back to `file.path` when the electronAPI helper is absent
+ * (Electron < 32, or jsdom tests without the bridge).
+ *
+ * @param {File} file - File object from a file input's files list
+ * @returns {string | undefined} Absolute filesystem path when resolvable
