Summary

Build a web-based pixel editor integrated into the admin panel so users can create and edit sprite assets directly in the browser without needing external tools.

Scope

Sprites only (500x333 px) — backgrounds (1536x1024) are too large for pixel editing and should remain upload-only.

Planned Features

Tools

Pencil — draw individual pixels
Eraser — clear pixels to transparent
Color picker — select from palette or pick from canvas
Fill bucket — flood fill a region
Grid overlay — toggle pixel grid for precision

Core Features

Zoom and pan for detailed work
Undo/redo history
Export at exact sprite dimensions (500x333 PNG)
Load existing sprite for editing

Technical Approach

Vanilla JS with Canvas2D — no external dependencies
Match the retro aesthetic of the admin panel
Estimated 1000-1500 lines of JS
Integrated as a modal or dedicated section in the Sprites tab

Dependencies

Should be tackled after containerization (#4) is complete
