LinkedIn's unauthenticated public profile only exposes name, summary (truncated),
current employer name, and certifications. Past roles, education, and skills are
blurred server-side behind a login wall — not a scraper limitation.
- Update selectors: data-section='summary' (was 'about'), .profile-section-card
for certs, .visible-list for current experience entry
- Strip login-wall noise injected into summary text after 'see more'
- Skip aria-hidden blurred placeholder experience items
- Add info callout in UI directing users to data export zip for full history
