/**
 * PixIndex - table of contents module for Joomla
 *
 * Fonts and colors always come from the template: this file never sets a font
 * and only derives colors from currentColor, the theme text color (read by the
 * script into --pixindex-text) or the system colors.
 *
 * - Cosmetic rules are wrapped in :where() (zero specificity): any template or
 *   custom rule wins without !important.
 * - Functional rules (list markers, current section, hidden states, sticky,
 *   panel) keep a low specificity, just enough to beat the framework resets.
 * - Sizes and colors can be changed with custom properties (on :root or .pixindex):
 *   --pixindex-indent, --pixindex-item-gap, --pixindex-active-weight,
 *   --pixindex-active-bg, --pixindex-active-bar, --pixindex-active-thickness,
 *   --pixindex-hover-bg, --pixindex-glass-bg, --pixindex-glass-border,
 *   --pixindex-glass-blur, --pixindex-glass-shadow, --pixindex-border-color,
 *   --pixindex-radius, --pixindex-padding, --pixindex-duration,
 *   --pixindex-sticky-top, --pixindex-max-height, --pixindex-panel-width,
 *   --pixindex-panel-bg, --pixindex-panel-color, --pixindex-fab-offset,
 *   --pixindex-backdrop.
