xfce-mirror/xfce4-sensors-plugin — reverse-engineered prompt

Build me an Xfce panel plugin that shows my computer’s hardware sensor readings directly in the panel, like temperatures, fan speeds, and other values the system exposes.

It should work with the Xfce 4 panel, read values from common Linux sensor sources such as lm sensors, ACPI, hddtemp, and NVIDIA tools when they’re available, and keep working even if some of those optional tools aren’t installed. I want a simple preferences window where I can choose which sensors show up, how they’re labeled, and how often they update.

Please include support for basic notifications if a sensor gets too hot, and let the display be themeable with a CSS file in the user config folder or a system location. Make it build and install cleanly with Meson, and include clear install and uninstall commands in the README.
