Sveltekit fullstack Kanban app with drag & drop

I tried my hand at doing one of the "guru" challenges, and I'm quite happy with how things turned out.

I wrote a summary of the difficulties I encountered in the project README, such as recreating a <select> from scratch (so that I can actually style it according to the design) without discarding the native behaviour of the original one.

This was my first time doing anything backend-related if we don't count some tinkering with Wordpress, so some feedback on that part in particular would be greatly appreciated.

I would also like to bring some attention to the drag & drop feature of the task cards, as that's the part I struggled with the most. It only works with a mouse. I deactivated it on touch screen devices because dragging the screen is already used to scroll the task section: I thought having the same action causing two different things depending on whether the tap started on a task card or in the small space between them would create a poor user experience.
