Regenerative Garden Planner
Game-like planner for laying out regenerative gardens on a to-scale plot. A deterministic TypeScript rules engine, decoupled from the React UI, evaluates companion pairings, spacing, and sun exposure in real time and explains every result using a 16-species dataset sourced from university extension research. Supabase (PostgreSQL with row-level security) powers Google and magic-link auth with debounced, retrying autosave, and saved data is versioned and validated on load. Backed by 250 Vitest tests and GitHub Actions CI.
