/**
 * Print flow: assemble the shared print document (slides / notes / handouts /
 * outline) and hand it to a print surface. All the pure logic is shared and
 * DOMPurify-hardened: `validatePrintSettings` normalises the caller's partial
 * settings, `computeSlideIndices` / `computeColorFilter` resolve the range and
 * colour mode, the `build*Html` helpers produce the escaped body markup, and
 * `buildPrintHtmlDocument` sanitises + assembles the final document. This
 * module (the Svelte counterpart of Vue's `usePrint`) exports direct slide
 * pages as vector SVG, rasterises notes/handout thumbnails, and opens the
 * print surface.
 *
 * **Print surface / popup-blocker caveats:** the default opener renders the
 * document into a hidden same-origin `<iframe srcdoc>` and calls
 * `contentWindow.print()`, so no popup window is involved and popup blockers
 * cannot interfere (`document.write` is avoided too). A host that prefers a
 * visible print window can inject its own {@link OpenPrintWindow} via the
 * controller deps; note that a `window.open`-based opener only succeeds inside
 * a user gesture (a click handler) and returns `null` under popup blockers,
 * in which case it should report `false` so the flow resolves `false` and the
 * host can surface "allow popups for this site" guidance.
