Side A introduces a new `/ui` endpoint with `HtmlUiAction` parsing, a reusable JSON form-template mechanism (`form_template.rs`), and refactors existing web-post handlers into shared functions so multiple UI actions can reuse the same logic. Side B meaningfully improves offline tooling by making log scans faster, exposing detailed parse errors, and adding `compile --ingest`, but those changes primarily enhance developer workflows rather than extending the application's core architecture and browser interaction model.
