Build a single-page app that helps users track how many hours of sunlight each of their houseplants receives per day.

The app displays a simple list of plants the user has added (name + ideal daily sunlight hours, e.g. "Monstera – 6 hrs"). For each plant there is a **+1 hr** button the user taps throughout the day to log sunlight accumulation. A small visual indicator (e.g. a colored progress bar or emoji) shows whether the plant is under-lit, on-target, or over-lit compared to its ideal.

Users can:
- **Add** a new plant entry with a name and an ideal sunlight hour target (1–12).
- **Increment** logged hours for any plant with a single button tap.
- **Reset** all plants' daily logged hours back to zero (simulating a new day).
- **Delete** a plant entry they no longer need.

All data must persist in `localStorage` so the list and current hour counts survive a page refresh. No backend, no auth, no external APIs — just a clean, usable single-page widget.
