- _focus_desc_editor: locate the description editor with multiple fallback
strategies instead of a single brittle selector; dump page screenshot/HTML
on failure for easier selector updates
- cookie_auth: positive verification via the upload button presence, with
login-page / intro-page / legacy checks as fallbacks
- close_guide_overlay: also remove the Joyride portal and spotlight layers
that intercept clicks
- add collection_name support to KSVideo
