/*
 * YottaMaster – AJAX Continuous Navigation Styles
 *
 * Uses the theme's own CSS custom properties so colours always match the
 * active palette / dark-mode without any extra effort:
 *
 *   --theme-palette-color-1  → accent / primary colour
 *   --theme-palette-color-7  → light surface (shimmer highlight)
 *   --theme-palette-color-8  → ultra-light surface (skeleton base)
 *   --theme-border-color     → subtle border used as skeleton background
 *   --theme-text-color       → body text colour
