/* ─── 26 Sep 2026 — PACKAGING: the PDF viewer (src/PackagingViewer.jsx) + PDF tiles ─────────────────
   Hugo: booklets, sleeves, labels for CD and vinyl are PDFs; they live in the Packaging asset category and
   open page by page here. ONE fixed size for the viewer (invariant #20): the pages scale inside the stage,
   every control keeps its width whatever it reads. Tokens only; each level sits a step LIGHTER than the
   one it sits on (panel → strip / stage → thumbnail), text 4.5:1 on its own fill; no tooltips. */
