# Arenas

Arenas are the playfield backgrounds — they change the visual environment without affecting hitboxes or game logic.

## Available Arenas

* **CLASSIC GRID** — Default, free for all
* **CLASSIC GREEN** — Free starter
* **JUNGLE RUINS** — Free starter
* **CRYSTAL CAVE** — Market item
* **LAVA ZONE** — Market item
* **GALAXY ARENA** — Market item
* **MATRIX GRID** — Market item
* **SPACE STATION** — Market item
* **VOID REALM** — Legendary market item

## Equipping an Arena

1. Open **LOCKER** → **BACKGROUND** tab
2. Tap an arena you own → EQUIP
3. Your next game uses it

CLASSIC GRID is the default — first in your locker list, fallback if no equip is set.

## Food + Snake Contrast

Food visibility is tuned per arena. Each food sprite has a dark anti-blend outline plus a warm glow halo so it stays readable across all arena backgrounds — even busy ones like LAVA ZONE or VOID REALM.
