/* SkyyCast Image to PDF (/tools/image-to-pdf).
 *
 * Loaded by that page only, after assets/sc-public.css AND
 * assets/sc-image-checker.css: reuses the checker's shared `ic-*` shell
 * (drop zone, buttons, card list, badges, facts grid) and the shared
 * `.ic-split` two-pane workspace, and only adds the `ip-*` pieces specific
 * to this tool -- the page-option controls, the per-item reorder buttons,
 * and the page-preview grid (a genuine representative render of each PDF
 * page, not a static mockup -- see sc-image-to-pdf.js computeLayout()).
 * All scoped under `.pub-site` and built from the `--pub-*` tokens: no new
 * colours, no new fonts, nothing on :root/html/body. Motion is limited to
 * short state transitions and is switched off under prefers-reduced-motion. */
