/**
* `<lr-json-schema-viewer>` — a recursive, selectable JSON Schema inspector with required-state,
* constraints, composition branches, `$ref` display, validation issues, cycle protection, and a
* configurable depth ceiling. It does not resolve remote references or validate values.
*
* Public schema records and issue collections take bounded, clone-owned readonly snapshots.
* Schema records recursively copy supported own data fields without invoking accessors; unsupported
* or unsafe branches are omitted while valid siblings remain. Create and reassign a new record or
* array after changes; mutating the assigned value does not update the view.
*
* @customElement lr-json-schema-viewer
* @event lr-schema-select - A schema node was activated. `detail: { schemaPath, schema }`.
* @csspart base - The named schema region.
* @csspart tree - The recursive schema tree.
* @csspart node - One schema node.
* @csspart node-selected - The selected schema node.
* @csspart node-trigger - A schema-node activation button.
* @csspart name - Property/branch name.
* @csspart type - Schema type badge.
* @csspart required - Required badge.
* @csspart description - Caller-supplied schema description.
* @csspart constraints - Recognized schema constraints.
* @csspart issue - One caller-supplied validation issue.
* @csspart limit - Resource-ceiling status shown when additional nodes are omitted.
* @csspart issue-limit - Resource-ceiling status shown when additional validation issues are omitted.
* @csspart empty - The empty state.
* @cssprop [--lr-schema-viewer-selected-border=var(--lr-color-brand)] - Selected node branch.
* @cssprop [--lr-schema-viewer-max-indent=var(--lr-size-12rem)] - Maximum visual indentation;
*   complete JSON Pointer paths and selection semantics remain unchanged at deeper levels.
* @cssprop [--lr-schema-viewer-error-border=var(--lr-color-danger)] - Error issue border.
* @cssprop [--lr-schema-viewer-error-bg=var(--lr-color-danger-quiet)] - Error issue background.
* @cssprop [--lr-schema-viewer-warning-border=var(--lr-color-warning)] - Warning issue border.
* @cssprop [--lr-schema-viewer-warning-bg=var(--lr-color-warning-quiet)] - Warning issue background.
* @cssprop [--lr-schema-viewer-info-border=var(--lr-color-brand)] - Info issue border.
* @cssprop [--lr-schema-viewer-info-bg=var(--lr-color-brand-quiet)] - Info issue background.
* @status stable
* @since 9.0.0
