Primary Move
Use blueprint blue bg-[#1e3a5f] for backgrounds paired with grid line background effects
Watch Out
Do not use warm-toned backgrounds
AI Implementation
Use the Hard Prompt by default to generate UI. Use the Design Spec to understand, modify, and review the style. Use the Creative Brief for early exploration.
Use this by default: copy it, append the concrete requirement, and let AI generate consistent production UI.

# Hard Prompt
## When To Use
Use this when you want AI to generate code with strict style consistency. It is the safest default for production UI.
## How To Use
- Copy the full prompt into ChatGPT, Claude, Cursor, or another coding assistant.
- Append the concrete product/page requirement after the prompt.
- After generation, check the forbidden rules and interaction states before accepting the output.
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
STYLE: Blueprint
TYPE: Engineering technical drawing interface
MUST USE:
- Blueprint blue background: bg-[#1e3a5f]
- White lines and text: text-white, border-white/30
- Monospace font: font-mono for all text
- uppercase tracking-widest for labels
- Grid background pattern for coordinates
- Orange annotations: text-[#ff6b35] for highlights
- Light blue secondary: text-[#a0c4e8]
- Corner markers on cards (L-shaped borders)
- Dashed lines for auxiliary elements: border-dashed
MUST AVOID:
- Warm-toned backgrounds
- Rounded/soft design elements
- Gradient fills
- Glow or neon effects
- Serif or handwritten fonts
- Large colored blocks
- Large border-radius (rounded-2xl+)
COLOR RULES:
- White line: #ffffff (primary elements)
- Blueprint blue: #1e3a5f (background)
- Light blue: #4a90d9, #a0c4e8 (secondary elements)
- Annotation orange: #ff6b35 (highlights, callouts)
SPECIAL EFFECTS:
- Grid background pattern (20px spacing)
- Corner bracket markers on containers
- Dimension lines with end markers
- Coordinate labels as decorative elements
Animation & Interaction Rules:
- CAD Precision: Interaction effects must be crisp and precise, prefer duration-100 (adjustable within 75-150ms range), avoiding sluggish ease-in-out.
- Crosshair Reveals: On hovering interactive elements, use before/after or corner markers to reveal crosshair and alignment hints.
- Blueprint Highlight: Default blue-white palette; active or confirm states can briefly light up engineering orange #ff6b35, but it must not dominate the main visual for long.
- Grid Interaction: Container hover can slightly increase grid line visibility (white lines to light blue lines), serving only as measurement feedback, not emotional animation.
## Absolute Bans (Match and Refuse)
If any of the following patterns appear, it is a style violation — rewrite without exception.
- use warm-toned backgrounds
- use rounded, soft design elements
- use gradient color fills (lines and fills should be solid colors)
- use glow effects or neon shadows
- use serif fonts or handwritten fonts
- use large areas of colored blocks
- use elements with overly large rounded corners rounded-2xl rounded-3xl
## Self-Check (Verify Before Shipping)
If any item fails, the style has drifted — fix before shipping.

Blueprint draws design inspiration from traditional cyanotype blueprint printing and modern engineering drafting. White lines on a blue background are its most iconic visual feature, while grid systems, annotation lines, and dimension markers give the interface a precise, professional, and trustworthy character.
