## [1.6.0] - 2026 February 25

Adds a GPU-accelerated WebGL 2.0 renderer as an alternative to the Canvas 2D renderer.

### Added

- `WebGL2D` class — WebGL 2.0 renderer using VAO/VBO batching and GLSL 300 es shaders.
  - `drawCellGrid` — renders the entire grid in a single draw call.
  - `drawAgentSet` — batched agent rendering grouped by shape style (≤3 draw calls per agent set).
  - `drawAgent` — single-agent draw fallback.
  - `drawCircle`, `drawRectangle`, `drawTriangle` — primitive drawing with optional fill, stroke, and rotation indicator.
  - `drawLine`, `drawPolygon`, `drawPolyline` — additional drawing primitives.
  - Alpha blending enabled by default.
- `AnimateWebGL2D` class — animation loop controller extending `WebGL2D`.
  - `play`, `pause`, `step`, `toggle`, `stepForward` methods.
  - Keyboard shortcuts: Space (play/pause), Enter (step).
  - FPS adjustable at runtime via custom events.
