Side A implements a substantive DSL redesign by changing the parser to support leading explanation blocks for votes, enforcing item-body placement, updating UI generation, validation, documentation, fixtures, and adding parser tests that reject legacy syntax and malformed inputs. Side B adds a useful browser UI dispatch layer (`POST /ui`), form-template infrastructure, and refactors shared handlers, but it is largely architectural plumbing for the web interface rather than a project-wide language and parsing change.
