Each file is theming only — colors, font, palette, prompt glyph. No keybinds, behavior flags, or identity. Drop into your own config and layer your own preferences on top.

Install

# 1. Install JetBrains Mono Nerd Font (used by Ghostty + Starship for icons)
brew install --cask font-jetbrains-mono-nerd-font

Terminal.app

open Phosphor-Neon-Dark.terminal
# Settings → Profiles → "Phosphor Neon Dark" → "Default"

Ghostty

# Either append directly to your config:
cat ghostty.config >> ~/.config/ghostty/config

# Or keep it modular by adding one line to your config:
# config-file = /absolute/path/to/ghostty.config

Starship

brew install starship

# Merge the palette + character blocks into your starship.toml.
# If you don't have one yet, you can start with these blocks as-is:
cat starship.toml >> ~/.config/starship.toml

The [palettes.phosphor] block defines named colors (purple, cyan, red, gray, fg) you can then reference in any module style — see the suggested assignments at the bottom of starship.toml.
