PocketTrail: three small things to notice outside, picked by a small open-weight model

This is a submission for the Hacktoberfest Week 1 "Touch Grass" challenge. PocketTrail is a small web app for people who want to look up from their phone for twenty minutes. You tell it how much time you have (10, 20 or 30 minutes), where you are going (a park, a garden, your neighborhood, or just a window or balcony), what it is like outside (daytime, evening, rainy) and your mood (calm, curious, creative). You can add a note like "stay seated, no photos". It gives you three short things to notice, with durations that add up to the time you picked.
