Module cotis_traits 

Cotis context trait implementations for HTMLRenderer.

These traits connect the renderer to the Cotis app loop:

Trait	Provides
RendererTextMeasuringProvider	Browser-based text measurement via renderer.js
CotisWindowContext	Viewport size in pixels
CotisFrameContext	Frame delta time in seconds
cotis_utils::traits::CotisRenderContext	Provided automatically via blanket impl when window + frame traits are implemented
RenderCompatibleWith	No-op layout init hook

Mouse input is implemented on HTMLRenderer directly (see the interactivity module). Keyboard state is available through HTMLInteractivity in the interactivity module (SimpleKeyboardProvider).
