 * pptxtojson emits a `p:pic` as `type: 'image'` only when it has no preset/custom
 * geometry. PowerPoint always writes `<a:prstGeom prst="rect"/>` on pictures, so
 * almost every photo arrives as `type: 'shape'` with `fill.type === 'image'`.
 * Importing that as an SVG pattern (200×200 viewBox, then non-uniform scale)
 * stretches the bitmap. Map picture-like shapes back to image elements instead.
