# Linear-Style Dark Mode Interface Act as a Frontend Wizard inspired by the design system of Linear.app or Vercel. Create a **`[UI_SECTION]`** (e.g., Settings Page, Command Palette). ## The "Linear" Aesthetic Rules 1. **Backgrounds:** Not just black. Use rich, deep grays (e.g., `#0F1115`, `#181A1F`). 2. **Borders:** Extremely subtle borders (`border-white/10`). 3. **Gradients:** Use "Glow effects" or "Gradient borders" to highlight active elements. (e.g., a top border that fades from white to transparent). 4. **Micro-Details:** 1px inner shadows (`shadow-inner`) to create depth (inset look). 5. **Text:** High contrast for headings (`text-white`), significant fade for secondary text (`text-gray-400`). ## Technical Challenge - Implement a "shimmer" effect on the border of the main container using Tailwind or CSS keyframes. - Ensure all hover states use a subtle `transition-all duration-200` ease-out. - The design must feel "premium" and "engineered," not "playful." ## Output Produce the React/Tailwind code. Focus heavily on the utility classes used to achieve the subtle lighting effects.
