+# 🎴 Character Card Standards
+
+This page explains the standard format and rules used for character cards.
+
+---
+
+## 📐 Card Dimensions
+
+- **Canvas Size:** `800x1120px`
+- **Print Equivalent:** 2.5 x 3.5 inches (at 300dpi, classic card format)
+
+---
+
+## 🧩 Layout Regions
+
+Each card is composed of the following sections:
+
+- **Top Name Bar** – Displays character name
+- **Series Text** – Indicates the collection or set the card belongs to
+- **Main Art Zone** – Character illustration
+- **Stats Row** – Shows 3 core stats:
+  - **Power**
+  - **Charm**
+  - **Wit**
+- **Flavor Text Box** – Optional quote or description
+- **Rarity Marker** – Icon, stars, or color code
+- **Artist name** - The creator of the Character illustration
+- **Kemoverse ID** - Unique SHA-256 code generated for the card, based on the information of the card (Ommiting art)
+
+
+---
+
+## 🌟 Rarity Tiers
+
+Each card belongs to a **rarity tier** which affects both appearance and stat limits.
+
+| Rarity       | Total Stats Cap | Visual Features Recommended                     |
+|--------------|------------------|-------------------------------------|
+| **Common**       | 100              | Plain template, minimal shine       |
+| **Uncommon**     | 140              | Slightly enhanced frame             |
+| **Rare**         | 180              | Decorative borders, mild shine      |
+| **Super Rare**   | 220              | Unique frame, vibrant shine         |
+| **Legendary**    | 250              | Custom art frames, animated effects |
+
+---
+
+## 🎲 Rarity Distribution Guidelines
+
+The following table shows an **example** of how many cards you might include *in a 20-card pack*, but the actual number of cards per rarity is flexible.
+
+What **matters most** is that rarities follow the **percentage limits** defined below.  
+These limits ensure balance across the entire card pool — regardless of total size.
+
+| Rarity       | Max % Allowed | Example (20 cards) | Weight  | Notes                                 |
+|--------------|----------------|--------------------|---------|----------------------------------------|
+| **Common**       | No upper limit | 10 cards (50%)       | 0.7     | Can exceed 50% of total if needed      |
+| **Uncommon**     | 20%             | 4 cards              | 0.2     | Should not exceed 20% of total         |
+| **Rare**         | 15%             | 3 cards              | 0.08    | Should not exceed 15% of total         |
+| **Super Rare**   | 10%             | 2 cards              | 0.015   | Should not exceed 10% of total         |
+| **Legendary**    | 5%              | 1 card               | 0.005   | Should not exceed 5% of total          |
+
+> ✅ You can include more cards overall (e.g. 40, 100, etc.),  
+> 🔒 But rarities from **Uncommon to Legendary** must **not exceed their percentage caps**.  
+> 🪶 **Common** cards are the only exception — they can scale freely and fill the remaining space.
+
+
+---
+
+## 🧮 Stat Allocation Rules
+
+Cards have **three core stats**: `Power`, `Charm`, and `Wit`.
+
+- The **sum** of these three stats **must not exceed** the max for the rarity tier.
+- Stats can be distributed however you want, as long as the total stays within the cap.
+- Minimum stat per field: `0`  
+- Maximum per stat: Not enforced, but try to keep cards balanced visually and mechanically.
+
+---
+
+## ✨ Rarity Visual Guide
+
+The standard cards have the following :
+
+- 🌱 Common – Gray
+- 🔸 Uncommon – Green
+- 🔷 Rare – Blue
+- 🔮 Epic – Gold
+- 🌈 Legendary – Purple
