/* my-skin.css — "My Skin": the user's own wallpaper, card texture, mascot and

 *
 * Everything keys off classes my-skin.js puts on <html> (NBDMySkinLogic.
 * htmlClasses): nothing here applies unless the user turned My Skin on and
 * has something to show. Values arrive as custom properties:
 *   --myskin-wallpaper / --myskin-texture   url("blob:…") or none
 *   --myskin-dim                            how much page colour covers the wallpaper
 *   --myskin-texture-strength               how much texture shows through cards
 *   --myskin-accent / --myskin-accent-fg    a contrast-checked custom accent
 * It works over any colour theme: the dim veil and card tint use that theme's
 * own --bg and --s2, so text keeps the theme's contrast.
