# UI Style: Atompunk & Cold War Nuclear Futurism
Atompunk is the high-stakes, pre-transistor retro-futurism of the Cold War Nuclear Age (1945–1965). Built on heavy naval steel, cast phenolic bakelite, vacuum tubes, and convex cathode-ray tube (CRT) monitors, it envisions a high-energy technological future powered by atomic fission and rocket engines. Synthesized from historical civil-defense archives, Brookhaven National Laboratory instrumentation, and canonical media (*Fallout*, *The Iron Giant*, *Dr. Strangelove*).
---
## 🧭 When to Activate
- Designing dashboards, cockpits, telemetric monitors, devtools, or complex data applications requiring a tactile, military-industrial, or retro-futuristic Cold War aesthetic.
- Developing game interfaces, creative tools, or interactive applications inspired by the *Fallout* franchise, Project Orion, or mid-century nuclear research facilities.
- Demanding high contrast, rugged physical affordances, and zero generic modern SaaS tropes (eliminating rounded pastel pills, floating cards, and borderless flat surfaces).
---
## 🕰️ Definition, Lineage, and Timeline
- **Chronology:** 1945 (Trinity detonation and civilian nuclear optimism) to 1965 (the advent of microchips and integrated circuits).
- **Aesthetic Pillars:** Raygun Gothic, civil-defense engineering, Brookhaven and Oak Ridge national laboratories instrumentation, Project Plowshare, and *Popular Science* atomic-automobile forecasts (e.g., Ford Nucleon).
- **Physical Reality:** Pre-silicon technology. Amplification is thermionic (vacuum tubes); displays are CRT oscilloscopes with green P1 or amber P3 phosphor persistence; switching is electro-mechanical (knife switches, heavy rotary dials, bakelite toggles); enclosures are heavy-gauge painted steel with structural hex-bolts and rivets.
- **Distinction from Neighbors:**
- Unlike **Dieselpunk** (1920–1940s: Art Deco, locomotive pistons, oily soot, exposed grease, steam pressure gauges), Atompunk is energized by nuclear isotopes, high-voltage vacuum coils, radar screens, and aerodynamic rocket aerodynamics.
- Unlike **Mid-Century Modern** (domestic minimalism, teak wood, organic Arne Jacobsen chairs), Atompunk represents industrialized government laboratories, control bunkers, and space-command silos.
- **Absolute Veto:** Atompunk is NOT a 1950s roadside diner or ice-cream parlor. Pastel milk-shakes, neon flamingo pinks, script fonts (*Pacifico*, *Lobster*), and kitsch jukeboxes are strictly prohibited.

## ✨ Micro-Interactions, Motion & Soundscapes
- **Ballistic Galvanometer:** Analog gauges must feature needle inertia (damping ratio $\zeta \approx 0.7$) with minor ballistic bounce before settling.
- **CRT Phosphor Warm-Up:** Displays fade in over 200ms with scanlines establishing first before luminescence expands.
- **Relay Click:** Switches and toggles produce sharp, instant visual depressions without floaty rubber easing.
---
## ♿ WCAG 2.2 Accessibility & High-Contrast Guardrails
- **Contrast Ratios:**
- P1 Green phosphor (`#27FF48`) on CRT black (`#06140A`): **14.8:1** (Surpasses WCAG AAA).
- Amber P3 phosphor (`#FF9900`) on Chassis (`#12181F`): **7.82:1** (Surpasses WCAG AAA).
- Hazard Yellow (`#FFC800`) on Bakelite (`#2B170E`): **11.2:1** (Surpasses WCAG AAA).
- **Dual-Contrast Focus Ring:**
`outline: 2px solid #27FF48; box-shadow: 0 0 0 1px #000;` ensures universal visibility across both dark chassis and amber readouts.
- **Reduced Motion:** Under `@media (prefers-reduced-motion: reduce)`, all cathode scanline flickers and needle vibrations are turned off; displays load at steady 100% opacity.
---
## 🚫 Anti-Patterns & Visual Sins (Anti-AI Slop Traps)
- ❌ **NEVER use ice-cream or candy pastel colors:** Flamingo pink, mint green, and butter yellow are strictly prohibited.
- ❌ **NEVER use script or cursive fonts:** Pacifico, Lobster, or 1950s diner scripts distort the nuclear survival genre.
- ❌ **NEVER create modern floating rounded cards:** Cards must appear as modular steel panels bolted into a 19-inch rack enclosure.
- ❌ **NEVER use soft modern SaaS gradients (Indigo/Fuchsia):** Atompunk relies on cathode emissions, glowing filaments, and lead-based industrial enamel finishes.
---
## 💡 Pairings & Cross-Style Synergies
- **Synergies:** Pairs naturally with **[ui-style-terminal-tui](../ui-style-terminal-tui/SKILL.md)** for low-level diagnostic logs and **[ui-style-blueprint-cad-schematic](../ui-style-blueprint-cad-schematic/SKILL.md)** for technical hardware schematics.
- **Avoid Colliding:** Never combine with **[ui-style-frutiger-aero](../ui-style-frutiger-aero/SKILL.md)** or **[ui-style-glassmorphism](../ui-style-glassmorphism/SKILL.md)**; the physical premise of vacuum tubes directly opposes transparent smartphone glass.

## Appearance and Interaction Verification
Specify whether CRT scanlines belong to the glass viewport or full diagnostic content; verify top/middle/bottom after resize and tune dark scanline/vignette composites without replacing green phosphor or steel/bakelite material cues.
