## Brand & Style

The design system is engineered for the **Xintong Smart Power Operation Management APP**, targeting power engineers and grid operators. The brand personality is **Professional, Efficient, and Industrial Tech**. It emphasizes reliability through a structured, high-density interface that transforms complex electrical data into actionable insights.

The design style is a blend of **Corporate Modern** and **Information-Dense Minimalism**. It utilizes a "Layered Surface" approach where data is organized into logical card blocks, using subtle elevations and clear semantic color-coding to denote system status. The aesthetic is clean and functional, avoiding decorative elements in favor of technical precision and rapid scanability.

- **Professionalism:** High-contrast typography and a restrained color palette.
- **Efficiency:** Condensed layouts that prioritize data visualization and task status.
- **Reliability:** Solid borders, consistent spacing, and clear state indicators.

## Colors

The color architecture is strictly functional, mapping specifically to the operation layers of the power management system. 

- **Primary (Deep Blue):** Reserved for core branding, navigation, and "Client" layer interactions.
- **Secondary (Purple):** Dedicated to "Gateway" operations and task-specific management.
- **Tertiary (Teal):** Used for "Service" layer success states and optimized performance indicators.
- **Neutral (Ink):** Used for primary text to ensure maximum legibility against light surfaces.

**Semantic Usage:**
- Use **status-warn (Amber)** for non-critical alerts or data synchronization states.
- Use **status-error (Red)** for critical power failures or permission denials.
- The **bg-page** provides a soft, low-strain canvas for long-duration monitoring, while **surface** (White) distinguishes interactive cards and data containers.

## Typography

This design system uses **Hanken Grotesk** as the primary typeface for its sharp, contemporary feel that bridges the gap between industrial and tech. **JetBrains Mono** is employed for technical data, device IDs, and numerical values to emphasize the system's engineering DNA.

- **Hierarchy:** Use `display-lg` for dashboard summaries. `title-sm` is the default for card headers.
- **Data Visualization:** All tabular data and technical strings must use `data-mono` for character alignment and clarity.
- **Mobile Adaptation:** For mobile screens, headlines should scale down to `headline-md-mobile` to maintain visual balance while preserving authority.

## Layout & Spacing

The layout utilizes a **Flexible Grid System** with a focus on logical grouping through card-based containment.

- **Grid:** A 12-column grid is used for desktop views, transitioning to a single-column stacked layout for mobile.
- **Rhythm:** An 8px-based spacing scale ensures vertical consistency. Use `lg (24px)` for outer card padding and `md (16px)` for internal element spacing.
- **Mobile Margins:** Standard mobile side margins are set to `md (16px)` to maximize screen real estate for dense data tables.
- **Sectioning:** Distinct operational modules should be separated by `xl (40px)` of vertical space to prevent cognitive overload.

## Elevation & Depth

This design system conveys hierarchy through **Tonal Layering** and **Subtle Ambient Shadows**. We avoid heavy skeuomorphism in favor of a "Flat-Plus" approach.

- **Base Layer:** The page background (`bg-page`) sits at the lowest elevation.
- **Mid Layer (Cards):** UI cards use a white surface with a subtle shadow (`0 4px 14px rgba(0,0,0,.07)`) to appear slightly lifted.
- **Interactive Layer:** On hover or active state, cards may transition to a higher elevation (`0 8px 28px rgba(0,0,0,.1)`) with a slight upward translation of -2px.
- **Overlays:** Modals and dropdowns use the highest z-index with a distinct backdrop blur to maintain focus on the task at hand.
- **Gradients:** Use soft radial gradients in the background (Blue/Purple) to create environmental depth without interfering with content legibility.

## Shapes

The shape language is **Rounded**, balancing industrial rigidity with modern software approachability.

- **Cards & Sections:** Use the standard `rounded-lg (1rem)` for primary containers.
- **Nodes & Blocks:** Architecture and data nodes use `rounded (0.5rem)` to fit more compactly within layouts.
- **Interactive Elements:** Buttons and tags use a "Pill-shape" (`rounded-xl` or 999px) to distinguish them from structural containers.
- **Borders:** Use `1px solid` with the `border-rule` color for most containers. Active states or primary focus areas may increase to `1.5px`.

## Components

**Buttons:**
- **Primary:** Solid `primary_color` with white text. Pill-shaped.
- **Secondary:** Transparent with `primary_color` border or subtle purple tint for operation tasks.
- **Danger:** Solid `status-error` for irreversible actions.

**Cards:**
- White background, `1px` border-rule, and `rounded-lg` corners. 
- Headers should have a `18px` internal padding and a bottom border to separate from the content body.

**Input Fields:**
- Soft white background with `1px` border. 
- Focused states should use a `primary_color` border with a subtle outer glow.

**Chips & Tags:**
- Used for status (e.g., "Active", "Offline").
- Backgrounds should use `8% opacity` versions of the semantic colors (Blue, Green, Red) with bolded text in the 100% opacity color.

**Data Visualization:**
- Charts should use the primary blue and secondary purple as the main data series colors.
- Use `data-mono` for all axis labels and tooltips to ensure technical accuracy.

**Status Indicators:**
- Small `7px` circular dots used within lists or architecture nodes to show real-time connectivity status.
