/**
 * Curated icon-name → Tabler icon map for plugin registrations.
 *
 * The frozen plugin contract (docs/plans/plugins/PLUGIN-API.md) only carries
 * opaque string icon names (`NavItem.icon`, `PluginPageChrome.icon`) — plugins
 * never hold host component values. The host maps known names onto first-party
 * glyphs here; unknown or missing names fall back per surface (puzzle piece in
 * the sidebar, no icon in the page topbar).
