Nerv Ui

Quick Start

Drop-in Stylesheet

<link rel="stylesheet" href="nerv-ui.css">

Contains all design tokens, CRT effects, and component classes. 808 lines, zero dependencies (except fonts).

Required Fonts

CRT Effects (standalone)

Just want the CRT look? Use components/crt-effects.css — scanlines, vignette, phosphor flicker, moving scan line. Add <div class="scan-line-overlay"></div> to your body.

Core Principles

1. The void is the default. Elements emerge from true black (#000), not a surface.
2. Color = function. Orange for labels/headers, green for nominal data, cyan for wireframes, red for alerts only.
3. Every visual conveys data. 3D scenes reference real metrics. No decorative wireframes.
4. Density = authority. More data per pixel = more credible.
5. Mechanical compression. Text squeezed via scaleX(0.78-0.85). Signature EVA look.
6. Bilingual is institutional. Japanese text = the org operates in Japanese. Not decoration.
7. CRT texture is always present. Scanlines, vignette, phosphor flicker.

Design Tokens

:root {

  --void:             #000000;
  --void-warm:        #080807;
  --void-panel:       #0C0C0A;

  /* NERV Orange — headers, labels, classification */
  --nerv-orange:      #FF9830;
  --nerv-orange-dim:  #C87020;
  --nerv-orange-hot:  #FFCC50;

  /* Nominal Green — data readouts, "system OK" */
  --data-green:       #50FF50;
  --data-green-dim:   #30BB30;

  /* Cyan — wireframes, spatial data */
  --wire-cyan:        #20F0FF;
  --wire-cyan-dim:    #10A0B0;

  /* Alert Red — emergencies only */
  --alert-red:        #FF3030;

Typography — NO HELVETICA

:root {
  /* Heavy display serif (EVA English titles) — weight 900, mechanically compressed */
  --font-title:  'Noto Serif Display', 'Times New Roman', serif;
  
  /* Japanese institutional (Matisse EB equivalent) */
  --font-mincho: 'Shippori Mincho B1', 'YuMincho', serif;
  
  /* Terminal/data readouts */
  --font-sys:    'JetBrains Mono', 'Cascadia Mono', monospace;
  
  /* WARNING stamps, emergency banners */
  --font-stamp:  'Saira Extra Condensed', 'Impact', sans-serif;
}

Mechanical compression (signature EVA):

.compressed-title {
  font-family: var(--font-title);
  font-weight: 900;
  transform: scaleX(0.82);
  transform-origin: left center;
  letter-spacing: 0.2em;
  text-transform: uppercase;
}

Components

Event Log Terminal

Scrolling blockchain event feed. Color-coded by type (DEPOSIT=green, BORROW=cyan, HARVEST=orange, REPAY=dim green, REDEEM=yellow, MINT=magenta). Shows timestamp, type, address/detail, amount, block number.

Demo: components/event-log.html

<div class="event-log">
  <div class="el-header">
    <span>Blockchain Event Log</span>
    <span class="el-count">42 events</span>
  </div>
  <div class="el-body" id="logBody">
    <div class="ev">
      <span class="ev-time">12:04:22</span>
      <span class="ev-type deposit">DEPOSIT</span>
      <span class="ev-detail">0x7f2a…4c3b → alETH Vault</span>
      <span class="ev-amount">142.5 ETH</span>
      <span class="ev-block">#19284721</span>
    </div>
  </div>
</div>

Vault Card

EVA Unit-style status card for protocol vaults. Compressed serif title + Japanese katakana name + key-value stat rows.

Demo: components/vault-card.html

<div class="panel">
  <div class="panel-header">
    <span>Unit-00 — alETH</span>
    <span class="tag"><span class="led green"></span>Operational</span>
  </div>
  <div class="vault-card">
    <div class="vc-id">Primary — Ethereum</div>
    <div class="vc-name">自己返済型ＥＴＨ</div>
    <div class="vc-row"><span class="lbl">TVL</span><span class="val">$142.8M</span></div>
    <!-- ... more rows ... -->
  </div>
</div>

MAGI Oracle Consensus

Three-source oracle display (Chainlink, Uniswap TWAP, Internal) with price, data freshness, and agreement status. Updates in real-time.

Demo: components/magi-oracle.html

Metrics Grid

Dense 2×N grid of key protocol numbers. Uses the .highlight modifier for important values and .zero for the always-zero liquidation counter.

Demo: components/metrics-grid.html

Data Tables

NERV-styled tables for strategy performance and transmuter status. Orange headers, green data, hover highlighting, progress bars for utilization.

Demo: components/data-table.html

3D MAGI Data Analysis (Three.js)

The hero visualization. Requires Three.js via CDN importmap. Elements:

• Cyan wireframe mesh — undulating yield surface with numbered vertex labels
• Orange organic curves — 30 flow lines rising from mesh, independently swaying
• Glowing tip dots — pulsing orange spheres at curve endpoints
• Flanking bar columns — orange metric bars on left/right with wireframe outlines
• Green background particles — depth-adding scattered points
• Slow camera orbit

See demo.html Three.js module for full implementation (~200 lines).

Emergency Mode

Toggle via data-mode="emergency" on <html>:

document.documentElement.dataset.mode = 'emergency';

Transforms: all green→red, cyan→red, scan line speeds up, emergency overlay appears, MAGI goes into conflict state.

Anti-Patterns

Accessibility

All color combinations pass WCAG AA:

• Orange #FF9830 on black: 8.2:1 ✅
• Green #50FF50 on black: 13.8:1 ✅
• Cyan #20F0FF on black: 13.1:1 ✅
• Red #FF3030 on black: 5.9:1 ✅

@media (prefers-reduced-motion: reduce) {
  body, .scan-line-overlay, [data-mode="emergency"] * {
    animation: none !important;
  }
}

The screen is off until data demands it. The void is the default state.
