Xerxisfy Elite Style Sheet (X2S)

Xerxisfy Elite Style Sheet (X2S) is a TypeScript-based CSS preprocessor and bundler designed for its custom `.x2s` stylesheet syntax. Currently at version 26.0.1, it actively develops and provides a robust CLI for compiling single `.x2s` files or entire directories into a single optimized CSS bundle. While no explicit release cadence is documented, the high major version suggests frequent and potentially significant updates. Key differentiators include unique features like `@context` for scoped global variables, `light(...) dark(...)` for theme baking, semantic layering via `layer:`, Xerx Guard locks (`@lock`) to prevent property overrides, and advanced container unit math (e.g., `cw`, `ch`). It also offers zero-config polyfilling for modern CSS features and automatic raster asset rewriting to WebP formats, making it a comprehensive tool for modern CSS development that extends beyond standard preprocessor capabilities like nesting, mixins, and control flow.
