/**
 * Page Designer — Image Block Placeholder
 * v1.0.0 (introduced in PAGE_DESIGNER_VERSION 2.6.72)
 *
 * Dedicated stylesheet for the Image Block placeholder logic. Kept
 * separate from the Image Settings Panel (pd_image_panel.css) and the
 * Image Picker (pd_image_picker.css). Own namespace: `pd-img-blk-*`.
 *
 * Grep-confirmed unused: `pd-img-blk-*` appears nowhere else in the
 * module prior to v1.0.0.
 *
 * This file is currently empty — the placeholder is purely an SVG
 * written into the GrapesJS image component's `src` attribute. No
 * extra CSS rules are required to render it. The file exists only so
 * the editor.php auto-loader's `<link>` tag for
 * assets/blocks/image/image.css does not 404.
