Inspect the current page DOM to auto-detect CSS selectors for UpGrad LXP elements. Run this on each key page (login, dashboard, course, track, class_list, class_detail) to map the real selectors, then apply them with apply_selectors.

Save discovered selector overrides to disk. These override the default guesses and persist across server restarts.
