/**
 * DreamNextAI KDP Tools — KDP Image Resizer styles (Tool #3).
 *
 * Self-contained like checker.css/formatter.css: a Resizer-only page
 * never enqueues checker.css or formatter.css (see class-assets.php),
 * so every class resizer.js's markup actually generates is defined
 * here too, even where it visually matches a class also defined by
 * another tool's stylesheet. Reuses the shared --dnai-* custom
 * properties from kdp-tools.css; nothing here is overridden outside
 * the `.dnai-kdp-resizer` ancestor selector where a class name isn't
 * already unique to this tool.
