A comprehensive static HTML collection manager for tracking vintage 1997 Bandai Carddass Pokémon cards.

I created this project during my free time after diving into collecting vintage Pokémon Carddass cards from 1997. Many of these cards come directly from Japan through auctions—it's quite the adventure: bidding, winning, and then patiently waiting for packages to arrive across the globe! I wanted something more engaging and visual than a boring Excel spreadsheet to track my collection, and this is what came to life. It's designed to make collecting more organized, enjoyable, and efficient.

The Problem: Managing a growing card collection with just spreadsheets is tedious and error-prone.
