/**
 * IframeEmbed — generic embeddable `<iframe>` block (Vimeo, Loom, Google
 * Slides/Docs, CodePen, Figma, dashboards, etc.).
 *
 * Distinct from the YouTube extension (which renders its own
 * `div[data-youtube-video]` wrapper). This node renders a responsive
 * `div[data-iframe] > iframe`. Only `https:` sources are accepted — the
 * sanitizer enforces the same rule on output so saved content stays safe.
 *
 * The wrapper carries an optional px `width` (inline style); the iframe fills it
 * at `width:100%`. A `null`/`100%` width means full width (responsive). The
 * editor adds resize handles via the shared embed resize NodeView.
