 * ExportUiState: reactive state behind the toolbar `ExportMenu` and the
 * `ExportProgressModal`. Svelte port of Vue's `useExportProgress` composable:
 * it owns the modal state (open / title / progress / status), the
 * `AbortController` the export loops check between slides, and wraps each
 * multi-slide export (PDF / GIF / WebM) in a `begin -> run -> end` envelope.
 * All percentage maths + status labels come from `pptx-viewer-shared`
 * (`export-progress.ts`) so every binding shows identical progress.
 *
 * PNG (single slide, fast) and print (opens its own surface) run without the
 * modal; the menu trigger still disables via {@link exporting} while they run.
