Stillroot: a quiet plant companion for my friend Rohan

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend. I built Stillroot, a quiet plant-care companion for my friend Rohan. I picked a small, everyday scenario for his gift: a few plants on a windowsill, a weekend away, and the question, “Will someone need to check the soil while I'm gone?” The pothos, monstera, and basil in the demo are imagined plants. The readings are synthetic, and the windowsill is a creative design premise. This is a working gift prototype; the next step is to put it in Rohan's hands and replace the sample assumptions with his actual routine.
