/* Light, modern theme - same palette as the Desktop Builders
   (builder_shared/ui/theme.py) for a consistent look across the whole
   platform. Every existing class name is kept as-is so no PHP page needs
   to change; a few new ones (.stat-grid/.stat-card, .auth-card, nav
   icons/active state) are added for extra polish where used. */
