Side A adds substantive application behavior: typed `{"$form:i32":...}` template substitution with tests, a new `next` navigation field for vote handling, vote-page routing/UI integration, and client-side support for vote sliders and redirects after recording a vote. Side B mainly refactors the CLI helper into a grouped, clickable panel with CSS updates and a defensive assertion that command strings are safe for embedding in single-quoted JavaScript, which is a useful UI improvement but has a narrower long-term impact.
