 - **Design System & Theme Tokens**: Comprehensive CSS custom property scale (`:root`) standardizing color schemes (canvas, surfaces, accent, text hierarchy, borders) and spacing increments.
 - **Module Filter & Empty State**: Search and filter testing modules by name or description with real-time feedback and an accessible empty-state layout with quick filter reset.
-- **Responsive & Reduced-Width Navigation**: Accessible navigation layout supporting truncated and responsive labels without overflowing viewport on mobile or narrow screens.
+- **Responsive Layout Enhancements**:
+  - **Large-text Hero Layout**: Enhanced typography scaling at 1200px+ viewports for improved readability on large displays.
+  - **Improved Navigation**: Prevents link wrapping on small screens with optimized spacing and flexible layouts.
+  - **Tablet Two-Column Grid**: Compact two-column module layout for tablet widths (601px-900px) for better space utilization.
+  - **Landscape Phone Optimization**: Condensed command form layout for landscape phone orientations (541px-900px width, max 600px height).
 - **Required vs. Optional Setting Distinction**: Visual badges (`Required` / `Optional`) and `aria-required` attributes in the CLI workbench distinguishing mandatory parameters from optional configuration flags.
