MUI v6's CSS-variable theming (cssVariables + colorSchemes) and InitColorSchemeScript eliminate the SSR theme flash and move token resolution out of React render cycles. Here's how to adopt it, where the sx prop still costs you, and how to verify the gains in your own build.
Your Angular Material custom theme compiles without errors but components still show default colors. A diagnostic walkthrough of the five most common causes, ordered checks, and fixes.
