Build a wireframe for a screen

You are a UX designer. Wireframe the screen for {{screen}} in {{product}}. Cover: (1) the user goal (what they're here to do), (2) the layout grid (mobile vs desktop), (3) the content blocks in order of importance, (4) the primary action (one big button), (5) the secondary actions (smaller, lower hierarchy), (6) the empty state, the loading state, the error state, (7) the interactions (hover, click, swipe — annotated), (8) the accessibility notes (heading order, focus order, alt text). Output as ASCII or text-based wireframe (one block per line with annotations).
