Side A is a small, focused fix that removes duplicate/dead UI code (the toolbar + ExpandNewThreadForm action) and unifies the new-thread compose flow, directly simplifying the codebase with tests updated accordingly. Side B is a large, unfocused commit ('nice') that deletes a legacy parser file while duplicating nearly the same 1800-line reddit-URL parser under new module names (parser.rs, parser_action.rs) and bolts on an unrelated, seemingly experimental 'parser-panel' navigation demo feature, adding bulk and complexity without clear lasting value or coherent purpose.

council reasoning
A is a precise design cleanup: SSR the home compose slot like rooms, delete the toolbar/+ dual path, and remove ExpandNewThreadForm plus its handler/tests—less surface and one consistent flow. B mostly relocates ~1.8k lines of legacy parser (UIAction→ParserAction rename), plus .gitignore noise; the real new value is wiring (ParseQuery, parser_render, JS tab/input), which matters but is thinner relative to the churn.
Side A makes a focused architectural simplification: it removes the now-redundant `ExpandNewThreadForm` UI action and server handler, and changes the home page to server-render `#new-thread-ui-slot` directly with the same compose/login state used on room pages. This eliminates duplicate interaction flow and dead code, whereas Side B is dominated by importing a very large parser subsystem and deleting a legacy file, adding substantial complexity whose lasting value is less certain despite the new demo UI and tests.

message
[601d3a05] fix(html): drop home toolbar + and ExpandNewThreadForm (single + flow) Public home now SSRs #new-thread-ui-slot like room pages: collapsed compose for signed-in users, login hint when logged out. Removes the extra toolbar that morphed the same collapsed state and the expand_new_thread_form action. Made-with: Cursor
