eBay Code Comparison Widget

Description

Widget to paste multiple codes (comma or newline separated), search each on eBay with filters (used, US only, shipping to 40356). Automatically removes 1-3 character segments from codes, and also removes a 4-character segment if it appears at the beginning. Includes car model selector (Alfa Romeo, Mazda, Hyundai, Lincoln) that applies code transformations (e.g., removes any two-letter combinations like AA/AB/AC/AD from beginning/end and leading/trailing 00 for Alfa Romeo; removes 01/02/03 from beginning/end for Mazda; removes 3 separate characters from end for Hyundai; removes dashes and applies multiple transformations for Lincoln). Click on any code to search it directly. Search results persist across page refreshes and new searches - only cleared when you manually hover Reset. Reset button triggers on hover: clears the calculator, pastes clipboard content without confirmation and immediately starts search.
