Cucumber Irrigation Frontend

Cucumber Irrigation Frontend Design System

Overview

This skill defines the frontend design patterns from the cucumber-irrigation project - a professional agricultural decision system UI. The design features:

• Gemini Dark Theme - Deep dark backgrounds with subtle accent colors
• Glass Morphism - Semi-transparent panels with blur effects
• Aurora Backgrounds - Animated gradient blobs for visual depth
• Modern React Stack - React 19 + TypeScript + Tailwind CSS + Zustand

Original Design References

IMPORTANT: The design system is derived from 5 HTML prototype files stored in the references/ folder of this skill. When building new pages, READ these files first to understand the exact implementation:

When asked to create a new page, always read the relevant cankao file from this skill's references folder to ensure design consistency.

Page Design Patterns

1. Dashboard / Command Center Pattern

The Dashboard uses a hero card + side widgets + chart grid layout.

Layout Structure:

┌─────────────────────────────────────────────────────┐
│ Top Bar: Date/Status + Environment Capsules        │
├───────────────────────────────┬─────────────────────┤
│                               │ Warning Card        │
│   Hero Decision Card (2/3)    ├─────────────────────┤
│   - Glow effect               │ Info Card           │
│   - Large number display      │ - Progress bar      │
│   - Stat pills                │                     │
│   - Action buttons            │                     │
├───────────────────────────────┴─────────────────────┤
│ Chart Card          │  Vision Comparison Card       │
│ - Trend lines       │  - Yesterday vs Today images  │
│ - Tab switching     │  - YOLO overlay boxes         │
│                     │  - % change badges            │
└─────────────────────┴───────────────────────────────┘

Best Practices

1. Color Usage

   • Use accent-primary (#A8C7FA blue) for primary CTAs and links
   • Use accent-success (#6DD58C green) for success states and primary actions
   • Use accent-purple (#D6BBFB) for AI-related elements
   • Always use semi-transparent backgrounds for overlays

2. Typography

   • Headlines: text-text-primary font-semibold
   • Body: text-text-secondary
   • Labels: text-text-muted text-xs uppercase tracking-wide
   • Data/Values: font-mono text-accent-primary

3. Spacing

   • Card padding: p-6 (1.5rem)
   • Section gaps: gap-6 (1.5rem)
   • Element gaps: gap-3 or gap-4

4. Borders & Radius

   • Cards: rounded-xl (1rem)
   • Buttons: rounded-lg (0.75rem)
   • Pills/Capsules: rounded-full
   • Default border: border-gemini-border

5. Hover States

   • Border lightens: hover:border-gemini-border-hover
   • Background elevates: hover:bg-gemini-surface-hover
   • Shadow deepens: hover:shadow-panel-hover
   • Use transition-all for smooth animations

6. Icons

   • Use Phosphor Icons (ph-* classes)
   • Icon colors should match their context
   • Size: text-lg or text-xl for UI icons
