* feat(nixpak): sandbox Steam and Heroic in ~/Gaming idols-ai stops preserving ~/.local/share/Steam, ~/.steam, ~/.config/heroic and their game data, which must be moved into ~/Gaming before deploying. Assisted-by: DeepSeek Harness (deepseek-flash) * refactor(nixpak): replace steam-fix.nu with sandboxed protontricks Assisted-by: DeepSeek Harness (claude-opus-5-5) * fix(nixpak): hide host documents and GTK config from game sandboxes Assisted-by: DeepSeek Harness (claude-opus-5-5) * docs(ai): locate the Steam library under ~/Gaming Assisted-by: DeepSeek Harness (claude-opus-5-5) * fix(umu-game): confine writes to ~/Gaming and keep foreign entries Assisted-by: DeepSeek Harness (claude-opus-5-5) * fix(nixpak): keep Steam and Heroic in the application launcher The wrappers only carried bin/, so neither launcher had a desktop entry after replacing programs.steam. Assisted-by: DeepSeek Harness (deepseek-flash) * fix(nixpak): give the game sandboxes a fontconfig that sees CJK fonts Steam rendered Chinese as tofu: the FHS layers build their own /etc/fonts, whose config lists only DejaVu and the XDG font directory, so neither the host fonts nor the FHS /usr/share/fonts were ever scanned. Point FONTCONFIG_FILE at a small config that includes /usr/share/fonts, and ship WenQuanYi Zen Hei and Noto Sans CJK in all three FHS layers. Assisted-by: DeepSeek Harness (deepseek-flash) * fix(nixpak): grant the game launchers a StatusNotifier tray icon Steam and Heroic register a tray icon over D-Bus, and the game sandboxes granted no StatusNotifierWatcher access, so the desktop shell had nothing to show for them. Enable desktopIntegration.tray for all three launchers and teach the policy suites to expect it. Assisted-by: DeepSeek Harness (deepseek-flash) * fix(nixpak): drop the duplicate host CJK font and tidy the font overrides Steam reads the fonts inside its own FHS layer, so the system-wide wqy_zenhei added for it no longer serves any sandbox. Give gaming-policy its own comment for FONTCONFIG_FILE instead of leaving it under the compat-tool one, make the desktop-base value a default, and note the SNI tray grant in the README table.
