AkurAI-Framework / crates/cli/src/cmd_new.rs

Latest change efd5eb833824dca5c86104004c11bc6d39ff1a72 - feat(template): pure-std SSR template engine + component showcase by Ólafur Búi Ólafsson

//! `akurai new <path>` — bootstrap a fresh project from embedded templates.
//!
//! Templates are baked into the binary with `include_str!`, so a single
//! executable can scaffold a complete project anywhere with no network or
//! extra files.
