- Rename package fablednetmon → fabledscryer throughout - Multi-dashboard: ownership, per-user defaults, HTMX edit (add/remove/reorder) - Read-only share tokens scoped to individual dashboards - Dashboard edit is HTMX-driven (no page reloads) - Plugin management system: remote catalog, download/install, hot-reload, in-app restart - plugin_index.py: fetch/cache remote index.yaml; default URL → bvandeusen/fabledscryer-plugins - plugin_manager.py: download_and_install_plugin, hot_reload_plugin, restart_app - ZIP extraction handles GitHub archive formats (name-v1.0.0/, name-main/) - Settings split into tabbed sections: General, Notifications, Ansible, Plugins - Plugins tab: catalog browser (HTMX), install/activate/update/restart actions - UI/branding: dark palette (#07071a), crystal ball SVG logo, animated star field, Libertinus Serif applied to headings, nav, labels, and section titles - Widget registry (core/widgets.py) for dashboard plugin integration - UPS widget.html (dashboard card) and settings/_tabs.html include - Migrations 0005–0008: dashboards, is_default, ownership, share tokens - docs/plugins/: writing-a-plugin.md updated with publishing guide, index.yaml.example template for fabledscryer-plugins repo Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
