Regex results filter + price sorting for eBay S-Card layout
Adds a live regex filter and price-sorting controls to eBay’s newer S-Card search results layout. The script inserts a small toolbar above the results where you can type any regular expression to instantly hide items that don’t match the title or subtitle text. It also includes a three-stage price sorter (original order, low-to-high, high-to-low) that rearranges only the real visible cards and never touches eBay’s hidden duplicate markup. Your last-used regex pattern is saved automatically, updates are applied as new items load, and everything works seamlessly with eBay’s infinite scrolling and dynamic page rendering.
