- internal/config: typed Config struct loaded from env vars via godotenv; all fields from docs (listen addr, JWT, DB, storage, thumbs, import) - migrations/embed.go: embed FS so goose SQL files are baked into the binary - cmd/server/main.go: load config → connect pgxpool → goose migrations (embedded) → Gin server with GET /health returning 200 OK - .env.example: documents all required and optional env vars - go.mod: bump to Go 1.26, add gin/pgx/goose/godotenv as direct deps Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
