# OPC Manager Design System Summary

Project: 科普（慰心斋）OPC 工作台  
Purpose: single-project operating dashboard for sales, business proposals, operations, product versions, and finance.

## Design Direction

- Style: enterprise operations dashboard, not a marketing landing page.
- Priority: clarity, scan speed, table density, stable editing flows.
- Primary color: calm blue for navigation and primary actions.
- Status colors: red for risk, amber for pending, green for completed, slate for archived.
- Surface system: white content surfaces on a light slate background, thin borders, compact spacing.

## Layout Rules

- Default view is the overview dashboard.
- Use top tabs for primary modules.
- Use tables for sales and operations.
- Use cards only for repeated version entities: business proposals and product versions.
- Use right-side drawers for editable details.
- Use Recharts line charts for finance trends, with detail tables below.

## Component Rules

- Tables should fit meeting review scenarios: compact rows, visible status badges, latest activity.
- Drawers should contain editable fields and timelines without navigating away.
- File groups should show category, file name, preview, download, and upload affordances.
- Charts must use the same data as detail tables.
