🦋 SYNOPSIS 🦋

🌸 ARGUMENTS 🌸

💅 DESCRIPTION 💅

okay so the whole description is short and sweet: ucsi_init() registers all ports ucsi has and enables all notification events. no cap, that's the vibe — it's giving setup era, and the notifications are absolutely invited to the group chat ✨

ngl this is the init step, so it's kind of a big deal. no extra lore was added here — we're keeping the facts exactly as they are, fr fr 💜
