/* TributePoint — programme booklet viewer * * Presents a rasterised programme PDF as a booklet: one page at a time, a * thumbnail strip to jump around, zoom, and a fullscreen reader. * * Progressive enhancement. Without JavaScript the markup is a plain stack of * page images and stays perfectly readable — programme-viewer.js adds the * `is-ready` class, and every rule that hides or repositions anything is gated * behind it. A JS failure therefore degrades to the scrollable stack, never to * a blank card. * * Colours are inherited (currentColor / transparent) so the viewer sits inside * a light theme or a dark one without either needing to know about it. */ /* assets/css/program-builder.css caps `.prg-scroll` at 380px — right for a long * timeline list, wrong for full programme pages, which it cropped to their top * third. The viewer owns this override rather than the widget's inline
