    ...endpoints only—so your solution should rely on HTTP requests, lightweight headless browsing or official unauthenticated APIs where they still exist. Speed and reliability matter: I expect a fresh scrape of an average-sized profile in seconds, not minutes, with graceful fall-backs if any platform rate-limits. The code should be clean Python (requests/BeautifulSoup or Playwright if you must touch the DOM), clearly separated into platform modules so I can extend it later for new data points or additional networks. A simple CLI flag, REST endpoint or callable function that lets me say “scrape now” is all that’s required; no automatic scheduling for the moment. Deliverables • Fully-commented source code organised by platform • A or Pipfile ...

    ...immediately upon loading the Settings page. Because the page freezes instantly, I cannot access the "Custom JS" field to delete the code. What I have already tried: I have spent hours trying to resolve this with the help of AI (Gemini and Claude), using Chrome DevTools (F12), but without success. My attempts included: • Using "Pause script execution" in the Sources tab to stop the loop. • Setting "DOM Mutation Breakpoints" to catch the script. • Disabling JavaScript via the Command Menu. (This prevents GHL from loading at all, making the "Save" button unreachable). • Injecting MutationObserver = null via the Console on a stable page before navigating. • Using CPU Throttling to slow down the execution. Despite these ...
