CHORUS Services - Ultra-Minimalist Implementation Guide

Overview

This guide provides practical implementation details for the ultra-clean, minimalist aesthetic that aligns with the new Mobius ring logo and corporate color palette.

Core Design Principles

1. Radical Simplicity

• Remove everything unnecessary: Every element must serve a functional purpose
• Embrace white space: 50% more spacing than conventional designs
• Single accent per screen: Limit color usage to maintain focus
• Typography hierarchy: Achieved through size and weight, not color

2. Mobius Ring Inspiration

• Continuous flow: UI elements should flow naturally like the infinite loop
• Seamless transitions: 200ms ease-out transitions for all interactions
• Geometric precision: Clean lines and perfect proportions
• Subtle sophistication: Elegance through restraint

3. Subtle Color Implementation

• Base colors only: Use core brand colors in their pure form
• Opacity for states: Hover (80% opacity), disabled (40% opacity)
• Invisible borders: #FAFAFA for section separation without visual weight
• Natural paper warmth: #F5F5DC for comfortable background tones

Implementation Rules

DO

• Default to dark mode - All CHORUS applications should launch in dark mode
• Use generous white space (minimum 32px between major sections)
• Stick to the defined color palette exactly
• Maintain single accent color per interface
• Use the Mobius ring icon sparingly and purposefully
• Implement smooth 200ms transitions for all interactions
• Choose typography hierarchy over color for emphasis
• Use clean white text in dark mode (avoid yellowish paper colors)

DON'T

• Add shadows, gradients, or border-radius to any elements
• Use more than 2 colors on any single screen
• Create busy interfaces with multiple competing elements
• Use decorative elements that don't serve a function
• Implement complex animations or transitions
• Override the defined spacing system
• Default to light mode (dark mode is preferred)

Font Implementation

Google Fonts Import

@import url('https://fonts.googleapis.com/css2?family=Exo:ital,wght@0,100..900;1,100..900&family=Inter+Tight:ital,wght@0,100..900;1,100..900&family=Inconsolata:wght@200..900&display=swap');

Tailwind CSS Configuration

fontFamily: {
  sans: ["Inter Tight", "Inter", "system-ui", "sans-serif"],
  mono: ["Inconsolata", "ui-monospace", "monospace"],
  logo: ["Exo", "Inter Tight", "sans-serif"]
}

Font Usage Rules

• Exo Thin 100: Only for "CHORUS" logotypes and brand signatures
• Inter Tight: All headings, body text, navigation, UI elements
• Inconsolata: All code blocks, terminal output, technical documentation
• Grid-based spacing: Use mathematical precision for all layouts
• Strong hierarchy: Achieved through size and weight, never color

Dark Mode Implementation (Default)

Default Theme Preference

• Launch in dark mode: All CHORUS applications should default to dark mode
• Professional aesthetic: Dark mode conveys enterprise sophistication
• Brand alignment: Carbon black backgrounds align with CHORUS minimalism
• User preference: Dark mode is preferred for development tools and enterprise software

Dark Mode Color Implementation

• Backgrounds: Carbon black (#000000) → Mulberry variants → Subtle grays
• Text: Clean white (#FFFFFF) for primary text, purple-300 for secondary
• Accents: Mulberry (#0b0213) for primary actions, brand colors for states
• Borders: Subtle mulberry variants instead of grays where possible

Theme Toggle Behavior

• Default state: Applications launch with class="dark" on html element
• Persistence: Remember user's theme choice in localStorage
• Graceful fallback: Provide light mode as alternative option

Website Integration

Header (Dark Mode)

• Carbon black background with subtle mulberry border
• Single Mobius ring icon (no wordmark in navigation)
• Clean white typography at 16px weight 500
• 64px vertical padding for breathing room

Hero Section (Dark Mode)

• Carbon black or subtle mulberry background

• 128px padding top and bottom

Content Sections (Dark Mode)

• Carbon black backgrounds
• 32px padding on all sides
• Clean white text with purple accents
• 24px spacing between sections

Quality Assurance

Accessibility

• Touch targets minimum 44px for mobile accessibility

Performance

• Use CSS custom properties for consistent implementation
• Minimal CSS with focus on performance
