/* Selección de asientos (seatmap/select_seats.html) sobre la base Coccoa.

   Reemplaza a static/css/seat_selection.css (tema oscuro azul marino) con las
   mismas clases e ids: el marcado es contrato de static/js/seat_selection.js
   (26 ids por getElementById, clases generadas con innerHTML y las variables
   en línea --dot-color / --seat-color). Todo sale de los tokens --c-*.

   Se quedan como están, a propósito:
   - El lienzo del mapa (#stage-container) es oscuro en los dos modos: Konva
     pinta el borde de los asientos en blanco y no lee variables CSS.
   - Los colores de estado (mi selección, reservado, vendido, no disponible) y
     los de cada etapa los calculan Python y el JS: son semánticos. El fucsia de
     Coccoa solo va en acentos pequeños para no confundirse con «Vendido». */
