First devlog in the tower defense series. This week: project structure, rendering a basic grid, and defining the shared spec that C and C++ ports will follow.

## What worked

- Odin's explicit memory model made the render loop straightforward
- Keeping the game spec language-agnostic from day one

## What broke

- Pathfinding placeholder — towers can be placed anywhere for now
- No entity system yet; everything is in one update function

Next: basic tower placement and enemy waves.
