- TodoItem: flatten to single-line row layout — checkbox, title, pills, date/reset info, actions all inline. Use hover:bg-card-elevated instead of bordered card with shadow. - TodoList: tighten spacing from space-y-2 to space-y-0.5 - stylesheet.md: document list-view vs card-view convention — list pages use single-line rows, grid pages use multi-line cards Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
