# Adding Asset Sheets

## Quick Start

Follow this workflow when introducing a new sprite sheet (with or without construction variants):

1. Place PNGs in `/public/assets/`
2. Add new `BuildingType`/`Tool` entries + `TOOL_INFO` + `BUILDING_STATS` in `src/types/game.ts`
3. Configure the sprite pack in `src/lib/renderConfig.ts`
4. Update render logic to load and select the new sheet
5. Add tools to sidebar + mobile toolbar categories
6. Map tools to buildings in `src/context/GameContext.tsx`
7. Add building sizes in `src/lib/simulation.ts`
