Transfer crumb mixture to a non-stick deep 9" pie dish. Press firmly onto bottom and up sides of dish. Bake until firm and slightly darkened in color, 12–15 minutes. If crust slides down sides, gently press back up. Let cool.
Remove 12 cranberries and set aside. Bring remaining cranberries, 1 cup sugar, and 1/4 cup water to a boil in a large saucepan over medium-high heat. Reduce heat and simmer until cranberries burst and most of the liquid evaporates, 12–15 minutes. Let cool. Purée in a blender until smooth.
Cook purée, eggs, egg yolks, lime juice, salt, 1/2 cup sugar, and lime zest in a heatproof bowl set over a saucepan of simmering water (bowl should not touch water), stirring with a rubber spatula and scraping down sides of bowl often, until curd thickens and coats spatula, 8–10 minutes. Let cool until just warm.
Using an electric mixer on medium-high, beat curd, adding butter a piece at a time and incorporating after each addition, until curd looks lighter in color and texture, about 5 minutes total. Scrape into crust and chill until firm, about 2 hours.
Roll 12 reserved cranberries in a small bowl with about a tablespoon of corn syrup and dry them on a wire rack in the refrigerator for 30 minutes.
Toss the tacky dried cranberries in a bowl with 1/4 cup of sugar until the sugar is crusted all over. Serve topped on pie.
Plan ahead as this needs 2 hours to chill the pie.
