//! Project tasks: `cargo xtask <task>`.
//!
//! - `ci`      fmt check, clippy -D warnings, tests, layers, assets, wasm check
//! - `layers`  crate dependency layering check
//! - `assets`  every file under assets/ and docs/ has a row in ATTRIBUTION.md
//! - `parity`  menu-catalog coverage → docs/parity-checklist.md
//! - `version` print the version, or `version set X.Y.Z`
//! - `icon`    regenerate the app icon PNGs/ICO from assets/app-icon/figcraft.svg (needs resvg)
//! - `wasm`    check the core crates and web app for wasm32, and build the plugin SDK and examples
//! - `plugins` format-check, lint, test and build the plugin SDK and example plugins (`plugins/`, a
//!   workspace of its own) for wasm32: `<target>/plugins/dist/<example>/` holds each manifest and
//!   module, ready for Plugins ▸ Development ▸ Import plugin from manifest…
//! - `bench`   release-build timings at 1k/10k/50k layers (`bench 1000,10000` for other sizes) and
//!   with a synthetic design system used by 2,000 instances
