- Badge is now a link to the detail page with ?highlight=hashsize
- Detail page auto-scrolls to Recent Packets section
- Each advert shows its hash size badge (yellow if different from current)
- Detail page shows always-visible explanation banner (not hidden)
- Side pane badge links to detail page too
