Initial commit: NexusOS project + desktop theme baseline
Captures the known-good state after theme consolidation and consistency reconciliation: - NexusOS GTK/xfwm4/icon theme assets (assets/themes, management/Mint-Y-Nexus) - Tightened right-click menus, visible separators, no menu icons - assets/themes/install-theme.sh: idempotent restore of all wiring (symlinks, xfconf xsettings+xfwm4, GTK 3/4 settings.ini) - .gitignore excludes venv/ollama/models/runtime/db Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# install-theme.sh — restore the NexusOS desktop theme wiring.
|
||||
#
|
||||
# The theme *assets* live in this repo (assets/themes/, management/Mint-Y-Nexus/).
|
||||
# This script recreates everything OUTSIDE the repo that makes the desktop
|
||||
# actually use them: symlinks, xfconf (xsettings + xfwm4), and the canonical
|
||||
# lines in the GTK 3/4 settings.ini files.
|
||||
#
|
||||
# Idempotent and safe: re-running only fixes drift; any real file it would
|
||||
# replace with a symlink is backed up to <file>.bak-YYYYMMDD first.
|
||||
#
|
||||
# Usage: ./assets/themes/install-theme.sh (apply + reload)
|
||||
# ./assets/themes/install-theme.sh --no-reload
