okay so here's the whole call, literally:

       slot );

🎀 ARGUMENTS 🎀

• folioq — the segment you're querying, bestie 🫶
• slot — the slot number of the folio you're querying ✨

💅 DESCRIPTION 💅

Lowkey the whole job is this: determine if the first mark is set for the folio in the specified slot in a folio queue segment. That's it. It's giving "quick vibe check for one tiny mark" and honestly? Iconic. You point it at a folioq segment, you tell it which slot, and it tells you about that first mark. Periodt. 💅
