/* visionneuse.css — kit visionneuse, version 1.2 (10.11.2026, @c-website ; 1.2 : types groupés, panneau « Citer » ; repris de assets/css/site.css de fabioballi.net,
   règles .zv (visionneuse, 25.10.2026) et .zcm (commentaire d'un document), état du 10.11.2026).
   Couleurs : jetons --zv-*, pris des variables du site quand elles existent (mêmes noms que fabioballi.net : --ink, --muted,
   --line, --bg, --surface, --chip, --field-line, --btn, --brand-ink, --dark-panel, --dark-panel-ink, --focus, --link, --radius,
   --err-bg, --err-ink, --err-line, --ok-bg, --ok-ink), sinon des valeurs ci-dessous. Le mode sombre suit donc celui du site.
   Boutons et champs : styles de repli de spécificité nulle (:where) pour .btn, .field__input et .visually-hidden ; les règles
   du site, s'il en a, l'emportent. Mode léger du site (html[data-eco]) : les images de la visionneuse sont masquées. */
