Minor Changes

• 652f804: feat(pptx): layout-instantiation in applyEdits (lossless scale-with-variety)

  applyEdits now supports source: { layoutId, fills? } in a PlannedSlide —
  instantiating a fresh slide from one of the template's own layouts inside
  the lossless byte-patch path. Because the layout is already a part of source,
  the new slide binds to ppt/slideLayouts/<layoutId>.xml (inheriting theme /
  master / background chrome) while every other part stays byte-identical. This
  unlocks lossless and scale-with-variety in one deck: clone slides where you
  want the exact thing, instantiate from layouts where you want variety.

  Each layout placeholder is materialised as an addressable, positioned element
  with a deterministic id — layoutSlotElementId(layoutId, key) (exported) where
  key is the placeholderKey / summarizeLayouts slot key. Text/obj slots
  are populated from fills and editable via setText; picture slots become a
  <p:pic> with a transparent placeholder blip so setImage can repoint them;
  chart/table/other slots expose their geometry so the host fills them with
  addChart / addDiagram. Placeholder geometry is read EMU-native from the
  layout (falling back to the matching master slot), so it stays correct without a
  canvas-px round-trip. An unresolvable layoutId is surfaced via onWarning and
  the slide is skipped rather than shipped wrong.

• 652f804: feat(render): headless renderDeckToImages + deck.fontUsage font transparency

  Headless render-to-image (visual-QA loop). New browser-free renderer that
  draws what the editor draws — native charts (buildChartOption + ECharts
  SSR), diagrams (layoutDiagram), text/shapes/images/backgrounds in z-order —
  not the OOXML raster fallbacks. No Playwright/Chromium/DOM.

  • renderDeckToSvg(deck, opts?) → one composed SVG per slide (ECharts is
    loaded on demand, so it never bloats the editor bundle).
  • renderDeckToImages(deck, opts?) / renderSlideToImage(deck, i, opts?) /
    renderPptxToImages(bytes, opts?) → raster bytes. Rasterisation is an
    injected hook (opts.rasterizeSvg, e.g. @resvg/resvg-js); when omitted the
    default tries a dynamic @resvg/resvg-js import and throws a clear error if
    it isn't installed — so there's no hard native dependency.
  • opts: slides (1-based subset), dpi (canvas scales by dpi/96),
    format, maxWidth (thumbnail cap). Deterministic (no animation).

  Enables the host's render → fresh-eyes inspect → targeted applyEdits fix →
  re-render cycle, rendering a final applyEdits output directly.

  Font transparency. parsePptx now stamps deck.fontUsage: { family, embedded }[] — every font family the deck's text uses, flagged
  whether the source PPTX actually embeds it (<p:embeddedFontLst> → a real
  ppt/fonts/* part) or merely references it (system-fallback risk on
  viewers that don't ship the brand font). Hosts use it to warn at generation
  time ("missing fonts for some ppts"). It's a read-only diagnostic, distinct from
  deck.fonts (the embeddable payloads).
