/*
 * Shared customer-facing table-picker UI (booking/select.php, booking/ticket_booking.php).
 * Sparse absolute positioning (one node per occupied cell, none for empty space) —
 * same technique as store/includes/table_grid_render.php. Themed with the site's
 * real vcon CSS variables (assets/css/theme-vcon.css) instead of each page's old
 * hardcoded neon/Bootstrap-light colors. Modifier names (.is-taken/.is-selected)
 * reuse the vocabulary already defined (but unused) in theme-vcon.css's .seat rules.
