💖 Members 💖

• version — The cmd db version. that's the vibe.
• magic — constant expected in the database. iconic little signature energy.
• header — array of resources. yes bestie, it's giving organized.
• checksum — checksum for the header. Unused. not me pointing at the unused field 👀
• reserved — reserved memory. leave it alone, respectfully.
• data — driver specific data. the driver's own little corner 🫶

heads up: checksum says Unused, so don't go assigning it main character energy. 💀
