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>

Composes each variant SVG from a shared master + a per-variant badge fragment,

then rasterizes each to PNG at 16/22/24/32/48/64/128 and drops the result into
