//! Compile-stage processor pipeline for RWE templates.
//!
//! Processors are optional features that transform template HTML before final
//! compile artifacts are produced.
//!
//! Current processors:
//!
//! - `tailwind`: Tailwind-like utility token compiler
//! - `markdown`: Markdown block conversion (`<markdown>...</markdown>`)
