 - **Automatic dark mode** — via `prefers-color-scheme` and `light-dark()`
 - **OKLCH color system** — perceptually uniform, fully customizable via SCSS config

 The final output is well under all budget targets. The `light-dark()` function and CSS cascade layers compress extremely well because they reuse the same variable names repeatedly.
