# Viz FPS Harness

A simple Canvas benchmark to evaluate tile rendering performance (FPS), DPR scaling, and animation cost for GlowTrack.

## Use
- Open `index.html` in a browser (mobile preferred).
- Adjust:
  - Tiles: 30–365
  - Animate: on/off
  - Device Pixel Ratio: 1–3
- Observe FPS and rendering smoothness.

## Goals
- Validate 60 fps target for typical grids.
- Identify breakpoints for fallbacks (reduced motion, static render).
