A static HTML preview of the redesigned Relationship Leads surface — the queue
where requesters triage warm-intro opportunities. The default lead view is cards;
a toggle on the toolbar swaps to a dense table modeled on the connector dashboard.
Shared chrome lives in shared/chrome.js; lead mock data lives in
shared/leads-data.js; visual tokens come from
../settings/shared/styles.css with overrides in
shared/leads.css.
