//! impeccable-hook: the design hook verbs (`hook`, `hook-before-edit`,
//! `hooks` / `hook-admin`), ported from `skill/scripts/hook.mjs`,
//! `hook-before-edit.mjs`, `hook-admin.mjs`, and `hook-lib.mjs`.
//!
//! The regex engine and design-system loader come from `impeccable-detect`;
//! the static HTML engine is reached through the `HtmlEngine` seam the `cli`
//! binary wires in (crates/html), so `.html` targets and configured
//! html-engine template extensions get the same DOM rules the JS applied.
//! The native-platform gate reads PRODUCT.md through `impeccable-context`'s
//! `resolve_context` / `extract_platform` (only the platform is observable,
//! so the rest of `loadContext` is skipped).
