The wall-framing takeoff's budget reads about fifty typed price names, and the page only listed them in a paragraph. Today the budget card gained an "Add a price line" dropdown: pick a name, press Add, and name, is appended to the price box (once; a repeat click does nothing). No prices are shipped; you still type your own.
Checked by clicking it in headless Chromium (eval-browser-click.mjs): one line added after two clicks, the existing budget and saved-plan checks still pass, zero page errors.
