What I set out to solve:
Pure Canvas rendering: Direct control over pixel projection, rendering loop, and double-buffering without DOM thrashing.
60 FPS smoothness: Viewport culling so panning across thousands of historical ticks doesn't choke the browser.
Clean separation of layers: Separated the background grid, main candles, crosshair overlay, and indicator pipelines so rendering one doesn't force a full repaint of everything.
Zero vendor lock-in: A clean, standalone library designed for developers who just want full control of their charting stack.
It's still in active development, but the core engine, multi-timeframe candle rendering, dynamic price/time scaling, and interactions are working.
