/* BioStudio AI — taskbar enhancements (js/core/taskbar-plus.js, taskbar-shelf.js).
 *
 * Look-and-feel rules are gated by html.fx-tb-* classes that
 * js/platform/visual-effects.js sets from Settings → Visual effects:
 *   fx-tb-float     floating glass Windows taskbar
 *   fx-tb-magnify   macOS Dock magnification
 *   fx-tb-adaptive  compact while a window is maximized, tint from the focused window
 *   fx-tb-motion    launch bounce, attention pulse, reorder animation
 * Live progress, attention rings, preview actions and the shelf are functional
 * and always present. The mobile shell is excluded from every visual rule.
