Add "Komponenten in Formularen" section to boundaries-ui.md with rules for core button classes, margin resets, checkbox sizing, sticky positioning, icon-only buttons, responsive grids, and CSS variables. Add matching quick-reference bullets to CLAUDE.md UI Patterns section. Fix breadcrumb wrapping: nowrap + overflow hidden + flex-shrink for single-line behavior. Add data-tab-panel-wide opt-out for full-width tab panels (default 70ch). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
