🌸 Detailed Description 🌸

A magnet needle for compass widgets. fr fr, that's her job description and she ate.

A magnet needle points to two opposite directions indicating north and south. two directions!! she's pointing at BOTH of them, at the same time, no cap. main character behavior honestly. 🧭💖

The following colors are used:

• QColorGroup::Light — used for pointing south ❄️
• QColorGroup::Dark — used for pointing north 🔥
• QColorGroup::Base — the knob (ThinStyle only). yeah she's got a lil knob and only the thin girlies get to have it. 🎀
