/* The photo viewer (static/js/components/photo-viewer.js; owner, 23 Oct 2026): the picture as large as
   the screen allows, a small glass strip centred under it — five or six rounded thumbs in view, the one
   on show ringed, one "3 / 14" counter — never over the picture's top. Tokens only; text and icons on
   the media glass are --ds-on-media. Used by the Library's sets and pictures, a brand's products and
   characters, the Agent's attached pictures. */
