/* css/xp-coffrets.css — COFFRETS page, on css/xp-page.css (3D shell) + css/shop.css + css/shop-content.css. The charter: the
   page is the sage of the packaging (the slab's studio), the cards blanc cassé with a hairline, photos in arched niches.
   The coffrets are opaque paper cards (name, price, line, honest composition note, « Ajouter » + « Personnaliser »);
   the photo frozen in its ice slab is the 3D part (js/xp/pages/coffrets.js):
     html.xpp-3d, ≥ 1024 px : cards in the left column, the slab in the sticky .cof-stage on the right;
     html.xpp-3d, < 1024 px : each card's <figure> is the slab's stage (the photo is its poster until the slab is live);
     html.xpp-flat          : the figures are plain photo frames beside (desktop) / above (phones) the cards. */
