 | `library/components/legends/LegendMobile.vue` | Mobile bottom-sheet legend chrome (drag/collapse/detail) wrapping the same LegendRows/SemanticTreeLegend/PeopleGroupDetail. | All CSS lives in a useShadowStyles template literal — a stray backtick in its comments silently blanks the whole mobile stylesheet. |
 | `library/components/legends/LegendRows.vue` | Flat-grid legend table: colored clickable filter rows, count/population columns, collapsible children, sticky title + totals footer. Emits filter-click. | ONE flat CSS grid with subgrid rows (spec: documentation/legend-spec.md); `.lrg-item` wrappers are display:contents on desktop only for LegendMobile compat — don't add layout to them. Never use scrollIntoView (host-page scroll regression 554bf10). |
 | `library/components/legends/LegendTools.vue` | Floating pill toolbar (auto-fly tour + clusters toggle) above the desktop legend card. Emits legend-row-fly. | Only renders for doxa-regions / language-family legend types; must stay a SIBLING of LegendDesktop (own `.lt-` CSS namespace); flight/cluster state lives in injected mapStore; hidden below 768px. |
-| `library/components/legends/SemanticTreeLegend.vue` | Hierarchical tabbed legend panel (collapsible, sortable, drill-up/down tree). Props: nodes, tabs, columns, open, exportEnabled; emits select/update:open/export. | Syncs selection via the per-instance mediator (usePplrInstance) when present, else local state; styles via useShadowStyles. Hidden kill-switch `SOW_EXPORT_BUTTON=false` hides the fully-wired Export menu across ALL bundles regardless of `:export-enabled`. |
