   CENTRAL FEEDBACK CONFIGURATION
   ----------------------------------------------------------------------------
   By default the suite stores all feedback in each user's own browser
   (localStorage) and reviewers share it via Export / Import. That needs no
   server and works behind any firewall.

   To ALSO collect feedback automatically into one central place, set
   FEEDBACK_ENDPOINT below to a URL that accepts an HTTP POST of JSON. This
   works with either:
     • a small backend on your host (Node/PHP/Python/ASP.NET) that appends the
       body to a feedback.json / .csv you can download, or
     • a Microsoft Power Automate "When an HTTP request is received" trigger
       that writes to a SharePoint list / Excel table.

   Leave it as an empty string to stay fully local (export/import only).
   See DEPLOYMENT.md for setup details and sample receivers.

window.FEEDBACK_ENDPOINT = '';

/* Best-effort send to the central endpoint. Never throws and never blocks the
   UI: feedback is always saved locally first by the caller, so a failed or
   disabled POST simply means "not centrally collected." Returns a Promise that
   resolves true on success, false otherwise. */
