-# Polymarket Macro Dashboard — Style Guide
-
-This document captures the visual, interaction, and layout conventions used in the Polymarket **Macro Dashboard**. It is intended as a reference for replicating or extending the Polymarket dashboard aesthetic in product, design, or engineering work.
-
----
-
-## 1. Design Philosophy
-
-- Data-first, probability-centric interface
-- Minimal visual noise; strong information hierarchy
-- Neutral, institutional tone suitable for finance and macro markets
-- Fast scannability over decorative elements
-
----
-
-## 2. Color System
-
-### Base Colors
-- **Background:** White / very light gray
-- **Primary Text:** Near-black
-- **Secondary Text:** Muted gray
-- **Accent:** Subtle blue for links, interactive states, and focus
-
-### Usage Principles
-- Percentages and odds are visually dominant
-- Color is used sparingly; emphasis comes from weight and spacing
-- No aggressive gradients or saturated backgrounds
-
----
-
-## 3. Typography
-
-- **Font family:** Modern sans-serif
-- **Headings:** Medium to bold weight
-- **Body text:** Regular weight, high legibility
-- **Numerical values:** Bold or semibold to anchor attention
-
-### Hierarchy
-1. Dashboard title
-2. Section headers
-3. Market question text
-4. Metadata / category labels
-
----
-
-## 4. Layout Structure
-
-### Global Layout
-- Fixed top navigation bar
-- Vertical scrolling content area
-- Card-based market listing
-
-### Page Structure
-```
-[Top Navigation]
-[Dashboard Selector]
-[Dashboard Title]
-[Market Sections]
-  ├─ Market Card
-  ├─ Market Card
-[Footer / Persistent Nav]
-```
-
-Spacing is consistent and generous, prioritizing clarity.
-
----
-
-## 5. Navigation
-
-### Top Navigation
-- Browse entry point
-- Horizontal category filters (Politics, Macro, Crypto, etc.)
-- Persistent search icon
-
-### Dashboard Selector
-- Inline tab-like controls (Macro, Elections, Fed Rates, etc.)
-- Minimal styling; relies on text weight and underline/contrast
-
----
-
-## 6. Market Cards
-
-Each market card contains:
-- Market question (headline)
-- Probability / chance percentage
-- Optional thumbnail or preview image
-- Category or context label
-
-### Card Characteristics
-- Uniform width
-- Light border or subtle shadow
-- Rounded corners
-- Clickable entire surface
-
----
-
-## 7. Information Hierarchy
-
-Priority order:
-1. Probability / odds
-2. Market question
-3. Category or context
-4. Supporting metadata
-
-The user should be able to scan probabilities without reading full text.
-
----
-
-## 8. Interaction Design
-
-- Hover states are subtle (slight background or border change)
-- Click targets are large and forgiving
-- No modal-heavy flows on the dashboard level
-- Transitions are fast and understated
-
----
-
-## 9. Motion & Feedback
-
-- Minimal animation
-- Instant feedback on navigation
-- No distracting micro-interactions
-- Emphasis on speed and responsiveness
-
----
-
-## 10. Accessibility & Readability
-
-- High contrast between text and background
-- Large tap targets for mobile
-- Clear separation between interactive and static elements
-
----
-
-## 11. Inferred Design Tokens (Example)
-
-```css
-:root {
-  --bg-primary: #ffffff;
-  --text-primary: #0a0a0a;
-  --text-secondary: #6b6b6b;
-  --accent: #1f6feb;
-
-  --radius-card: 8px;
-  --spacing-unit: 16px;
-
-  --font-body: system-ui, -apple-system, BlinkMacSystemFont, sans-serif;
-}
-```
-
----
-
-## 12. Summary
-
-The Polymarket Macro Dashboard prioritizes **trust, speed, and signal clarity**. Its design avoids ornamentation in favor of clean structure, strong typography, and probability-forward presentation. Any replication should preserve this restraint and information density.
