# Hard Prompt

Strictly follow the style rules below and maintain consistency. No style drift allowed.

## Requirements
- Prioritize style consistency first, then creative extension.
- When conflicts arise, treat prohibitions as the highest priority.
- Self-check before output: verify colors, typography, spacing, and interactions still match this style.

## Style Rules
# Constructivism (构成主义) Design System

> 苏联构成主义海报风格，强烈的红黑配色、对角线构图、几何块面、宣传性排版。

## 核心理念

构成主义（Constructivism）起源于1910年代的俄国先锋派艺术运动，在1920-30年代的苏联达到高峰。它主张"艺术为社会服务"，将视觉设计视为传达信息和动员大众的工具。

构成主义的核心视觉语言包括：强烈的对角线构图、几何块面的碰撞、红与黑的高对比配色。这些元素共同构建出一种充满能量与紧迫感的视觉体验，观者无法忽视。

排版在构成主义中扮演关键角色。文字不仅是内容载体，更是构图元素。大号粗体标题常以对角线或竖排方式出现，字重差异极端——超大标题与小号正文形成戏剧性对比。

配色严格受限：苏维埃红（#cc0000）、纯黑（#1a1a1a）和泛黄纸色（#f2e8d5）构成基本三色。金色和棕色作为点缀，暗示革命时期的印刷工艺与陈旧纸张。

在现代界面设计中，构成主义风格适合需要强烈视觉冲击的场景。倾斜的色块、硬边几何、大胆排版——这些元素让页面像一张革命海报，每个元素都在大声呼喊。

## [FORBIDDEN] 绝对禁止

以下 class 在本风格中**绝对禁止使用**，生成时必须检查并避免：

### 禁止的 Class
- `font-serif`
- `font-light`
- `font-normal`
- `font-medium`
- `rounded-sm`
- `rounded`
- `rounded-md`
- `rounded-lg`
- `rounded-xl`
- `rounded-2xl`
- `rounded-full`
- `shadow-sm`
- `shadow`
- `shadow-md`
- `shadow-lg`
- `shadow-xl`
- `bg-gradient-to-r`
- `bg-gradient-to-l`
- `bg-gradient-to-b`
- `bg-gradient-to-t`

### 禁止的模式
- 匹配 `^font-(?:serif|light|normal|medium)$`
- 匹配 `^rounded-(?!none)`
- 匹配 `^shadow-(?:sm|md|lg|xl|2xl)$`
- 匹配 `^bg-gradient-`
- 匹配 `^italic$`

### 禁止原因
- `font-serif`: Constructivism uses bold sans-serif industrial typography (font-sans font-black)
- `rounded-lg`: Constructivism demands sharp geometric edges (rounded-none)
- `shadow-md`: Constructivism uses hard offset shadows, not soft diffused ones
- `bg-gradient-to-r`: Constructivism uses flat solid color blocks, no gradients
- `font-light`: Constructivism requires heavy bold weights for propaganda impact

> WARNING: 如果你的代码中包含以上任何 class，必须立即替换。
