Design a conversion funnel block with Tailwind CSS. Inside a bordered rounded-2xl card, put a header row with a title, a muted date range and a small select for the segment. Below, five funnel rows stacked vertically: each row has a label and a count on the left in a fixed-width column, then a bar whose width is set inline as a percentage on a neutral-100 track, with the fill in neutral-900 and the conversion percentage printed inside the fill when it is wide enough or beside it when it is not. Between consecutive rows, a small indented note in muted red-ish text showing how many people dropped and the percentage lost. Under the rows, a summary strip with three figures — entered, completed and overall conversion — separated by vertical rules. Keep every number monospaced so the columns line up.
