Social event editing is more reliable and closer to walks. Event URLs update from the full title on blur and again on save, so a title like "Christmas Party" becomes christmas-party rather than a truncated slug. The venue editor is shared with walks, the Attendees tab is hidden in favour of bookings, and main tabs plus Event Details sections are filtered with URL query params.
Event Details with the All / Event / Venue / Description toggle (default All), title and clickable URL, and the framed Event and Venue sections
Title and read-only URL side by side — the slug is generated from the full title on blur and again on save
tab and sub-tab query params (default section is All)fields.attendees stays on the model for now
Filtering to Venue only — shared walk-style venue panel with social-event help text
Filtering to Description only — markdown description without the rest of the form
