Instagram story URL opens at first UNSEEN story, not the first

Navigating to instagram.com/stories/<user>/ in a logged-in browser starts the viewer at the first story that account has not yet viewed; stories seen on the phone are silently skipped, so a scraper that only presses ArrowRight misses them. Fix: after the viewer opens, press Escape then ArrowLeft repeatedly until the URL stops changing; if ArrowLeft lands on a different account's story, press ArrowRight once. Also log why the walk stopped (same URL after retries, moved to another account, no story, max frames) so short captures are diagnosable.
