Build me a Discord anime gacha game bot where people can collect, customize, trade, and manage cards right inside Discord.

I want the bot to feel fast and polished, with slash commands and Discord button interactions, plus support for both gateway and HTTP interaction setups. Players should be able to pull cards, view their collection, trade with others, use a shop, do little economy activities like coin flips, and customize cards with frames, dyes, and special effects. Make the card images render dynamically so each card can look unique.

Use Go for the backend, MariaDB for player and game data, and Docker so it can be deployed easily. If there’s a sensible way to cache common game data in memory, do that too. Make it structured so it could handle lots of users without slowing down, and include whatever basic admin or maintenance pieces are needed for a real Discord game. Look up current docs online if you need to.
