ghostty-deep-black-green-theme	Apply and configure the Ghostty deep black-green terminal theme on macOS: background #071f16, default light text, Sarasa Mono SC at 15pt. Use when the user asks to set up or replicate this Ghostty color scheme on a local Mac or a remote Mac over SSH, or to fix Ghostty background/font configuration on macOS.

Ghostty Deep Black-Green Theme

Overview

Apply this scheme to Ghostty on macOS:

• Background: #071f16 (deep black-green), solid — do not add opacity/blur unless asked
• Text: keep Ghostty default (light) — dark background makes it readable; do not set foreground unless the user explicitly wants a color
• Font: Sarasa Mono SC (English Iosevka + Chinese Source Han Sans, monospaced-aligned)
• Font size: 15

Config

background = #071f16
font-family = "Sarasa Mono SC"
grapheme-width-method = unicode
font-size = 15

macOS config files

Ghostty on macOS reads multiple config files; later/higher-priority files override earlier ones:

1. ~/.config/ghostty/config
2. ~/Library/Application Support/com.mitchellh.ghostty/config
3. ~/Library/Application Support/com.mitchellh.ghostty/config.ghostty

The Library files take priority over ~/.config/ghostty/config, and config.ghostty may be the actual effective file. Before applying, list and inspect all existing files. Verify effective settings with:

/Applications/Ghostty.app/Contents/MacOS/ghostty +show-config | grep -E '^(background|font-family|font-size|foreground|theme)'

If a higher-priority file still overrides background or font-size, remove the conflicting lines from that file (back it up first).

Apply

1. Ensure Sarasa Mono SC is installed in ~/Library/Fonts (file Sarasa-SuperTTC.ttc); if missing, copy it from another Mac with sshpass -p '<password>' scp ... (~793 MB) or download it.
2. Write the config lines into the effective config file(s).
3. Reload config with Cmd+Shift+,, or restart Ghostty if a setting does not apply.

Apply to a remote Mac over SSH

1. Back up the remote config first: cp "<config>" "<config>.bak.$(date +%Y%m%d)".
2. Pull it locally with sshpass -p '<password>' scp, edit with apply_patch, push it back with scp.
3. Verify the remote effective config, then ask the user to reload/restart Ghostty.
