🫶 ARGUMENTS 🫶

• crtc — the CRTC that's actually displaying stuff. your main character, fr fr 👑
• set_palette — the callback for programming the hardware gamma LUT. it's giving "you do the actual hardware work, i'll just hand you the values" energy 😭

---

💜 DESCRIPTION 💜

it programs an RGB332 palette to hardware. that's the tea 🍓 no cap, that's literally what it does — hands the hardware a default RGB332-style palette through your fancy little callback. iconic behavior honestly ✨
