/* The ONE photo viewer — pairs with assets/pt-photo-viewer.js (PHOTO-VIEWER-SPEC
   slice 1, 2026-10-29). Pages load this file and the script with plain tags and
   open the viewer through PTViewer.open(...); a page never builds its own.

   Placement per page is the --pt-viewer-z token (crew.html sets 92); the module
   carries no page placement. The stage's size has ONE owner: this file. Nothing
   in the script measures or sets the picture's box (DO NOT 13).

   Design tokens: declared on .ptv the way site-gallery.css declares them on
   .jv-gal (identical values), so the module renders the same on every page.
   No bare colour outside this block (DO NOT 24). */
