/* =====================================================================
 * Aluta — Timeline page click-to-view (custom PDF.js viewer)
 *
 * JS adds .aluta-tl-has-doc to any column/section whose ACF doc slot has
 * a file uploaded. Hover dims the column and shows a "View Document"
 * label; click opens the file in a PDF.js canvas viewer (no download
 * button, no print button). PDFs render to canvas — pages can be paged
 * + zoomed but the file is never exposed via a download surface.
