Shadowrun UI Aesthetic

This skill guides the creation of distinctive, production-grade UI that captures the cyberpunk aesthetic of Shadowrun while maintaining the usability required for a character management tool.

Design Philosophy

The Sixth World aesthetic: Corporate sleek meets street grit. Neon-lit interfaces emerging from darkness. Information density without visual clutter. Technology that feels both advanced and worn.

Balance two forces:

1. Precision & Density - Users spend hours in character creation; every pixel matters
2. Cyberpunk Atmosphere - The UI should feel like a runner's commlink interface

Color System

Primary Palette (Dark Mode Dominant)

/* Backgrounds - layered darkness */
--bg-base: #09090b; /* zinc-950 - deepest layer */
--bg-elevated: #18181b; /* zinc-900 - cards, panels */
--bg-surface: #27272a; /* zinc-800 - interactive surfaces */
--bg-hover: #3f3f46; /* zinc-700 - hover states */

/* Text hierarchy */
--text-primary: #fafafa; /* zinc-50 - headings, important */
--text-secondary: #a1a1aa; /* zinc-400 - body text */
--text-muted: #71717a; /* zinc-500 - labels, hints */

/* Borders */
--border-subtle: #27272a; /* zinc-800 */
--border-default: #3f3f46; /* zinc-700 */
--border-emphasis: #52525b; /* zinc-600 */

Accent Colors (Signature Shadowrun)

/* Matrix Green - Primary accent for tech/positive */
--accent-matrix: #00ff41;
--accent-matrix-dim: #00cc34;
--accent-matrix-glow: rgba(0, 255, 65, 0.15);

/* Corp Blue - Secondary accent, professional */
--accent-corp: #0ea5e9; /* sky-500 */
--accent-corp-dim: #0284c7;

/* Warning/Danger */
--accent-warning: #f59e0b; /* amber-500 */
--accent-danger: #ef4444; /* red-500 */

/* Magic Purple - For awakened content */
--accent-magic: #a855f7; /* purple-500 */

/* Resonance Cyan - For technomancer content */
--accent-resonance: #22d3ee; /* cyan-400 */

Usage Guidelines

• Matrix green for: success states, positive qualities, essence, magic rating
• Corp blue for: links, selected states, primary actions
• Warning amber for: budget overruns, caution states, negative qualities
• Danger red for: errors, forbidden items, damage
• Magic purple for: spells, rituals, foci, astral content
• Resonance cyan for: complex forms, sprites, matrix content

Typography

Font Stack

/* Body/UI - Clean, technical */
font-family:
  ui-sans-serif,
  system-ui,
  -apple-system,
  sans-serif;

/* Stats & Numbers - ALWAYS monospace */
font-family: ui-monospace, "SF Mono", "Fira Code", monospace;

Hierarchy Rules

1. Card titles: text-lg font-semibold - zinc-100
2. Section headers: text-sm font-medium uppercase tracking-wide - zinc-400
3. Body text: text-sm - zinc-300
4. Labels: text-xs font-medium - zinc-500
5. Stats/Numbers: font-mono text-base font-bold - zinc-100

Critical Rule: Monospace for Data

All numerical data MUST use monospace:

• Attribute values (BOD: 4)
• Skill ratings
• Costs (nuyen, karma, essence)
• Dice pools
• Damage codes

Spacing & Grid

4px Base Grid

All spacing uses multiples of 4px:

• gap-1 (4px) - between inline elements
• gap-2 (8px) - between related items
• gap-3 (12px) - between sections within a card
• gap-4 (16px) - between cards
• p-4 (16px) - card padding
• p-3 (12px) - compact card padding

Cyberpunk Accents (Use Sparingly)

Subtle Glow Effects

// For selected/active states only
<div className="border-sky-500 shadow-[0_0_10px_rgba(14,165,233,0.3)]">

// For important values (essence, magic)
<span className="text-emerald-400 drop-shadow-[0_0_4px_rgba(52,211,153,0.5)]">

Tech Panel Borders

// Accent corner for "high-tech" feel
<div className="relative rounded-lg border border-zinc-700 bg-zinc-900">
  <div className="absolute -top-px left-4 h-px w-8 bg-sky-500" />
  <div className="absolute -left-px top-4 h-8 w-px bg-sky-500" />
  {/* Content */}
</div>

Neon Card System (Dashboard & Lists)

The neon card system provides archetype-based visual identity with automatic light/dark mode adaptation. Defined in app/globals.css.

Archetype Colors (CSS Variables)

/* Available in :root and .dark with different intensities */
--accent-mage: #8b5cf6; /* Purple - full mages, aspected mages */
--accent-sam: #10b981; /* Green - street samurai, mundane */
--accent-rigger: #06b6d4; /* Cyan - riggers */
--accent-decker: #3b82f6; /* Blue - deckers, technomancers */
--accent-face: #f59e0b; /* Amber - faces, adepts */
--accent-campaign: #6366f1; /* Indigo - campaigns */

Neon Card Classes

// Base neon card - includes ::before accent bar
<div className="neon-card">
  {/* Content */}
</div>

// Archetype-specific cards (add glow effect)
<div className="neon-card neon-card-mage">   {/* Purple glow */}
<div className="neon-card neon-card-sam">    {/* Green glow */}
<div className="neon-card neon-card-rigger"> {/* Cyan glow */}
<div className="neon-card neon-card-decker"> {/* Blue glow */}
<div className="neon-card neon-card-face">   {/* Amber glow */}
<div className="neon-card neon-card-campaign">{/* Indigo glow */}

Archetype Detection Helper

import { Character } from "@/lib/types";

function getArchetypeCardClass(character: Character): string {
  const path = character.magicalPath;
  // Awakened - mage glow
  if (path === "full-mage" || path === "aspected-mage" || path === "explorer") {
    return "neon-card-mage";
  }
  // Adept - face/amber glow
  if (path === "adept") {
    return "neon-card-face";
  }
  // Technomancer - decker/blue glow
  if (path === "technomancer") {
    return "neon-card-decker";
  }
  // Mundane - sam/green glow (default)
  return "neon-card-sam";
}

// Usage
<div className={`neon-card ${getArchetypeCardClass(character)}`}>

Visual Dividers

// Neon divider with diamond center
<div className="neon-divider" />

// Section title with accent underline
<h2 className="section-title-accent">My Characters</h2>

// Alert banner with accent top bar
<div className="alert-banner-accent">
  Important message here
</div>

Grid Background

// Subtle tech grid overlay (use on containers)
<div className="bg-grid">{/* Dashboard content */}</div>

Stat Value Colors

<span className="stat-karma">25</span>    {/* Purple karma values */}
<span className="stat-nuyen">5,000¥</span> {/* Green nuyen values */}
<span className="stat-essence">5.4</span>  {/* Cyan essence values */}

Light vs Dark Mode Behavior

• Light mode: Subtle shadows, muted accent bars, professional appearance
• Dark mode: Full neon glow effects, vibrant accent colors, cyberpunk atmosphere

The CSS variables automatically adjust intensity based on theme.

Anti-Patterns (AVOID)

1. Generic Bootstrap/Material look - No default rounded buttons with solid colors
2. Excessive glow/neon - Reserve for key interactive moments
3. Light mode defaults - Dark mode is primary; light mode should still feel "tech"
4. Sans-serif for numbers - ALWAYS use monospace for stats
5. Fantasy RPG styling - No parchment textures, serif fonts, or medieval iconography
6. Cluttered dense layouts - Use whitespace strategically
7. Asymmetric padding - Maintain consistent internal spacing
8. Multiple accent colors at once - One accent per component
