 * FILE: public/assets/css/pricing_blocks.css
 * DESCRIPTION: Hoja de estilos centralizada para todos los bloques de 
 * presupuestos (CPQ - Configure, Price, Quote) y el Modal de Propuestas.
 * WHY IT EXISTS: Elimina la deuda técnica y la repetición de código (DRY). 
 * Garantiza que cualquier cambio visual en el cotizador o en el 
 * modal se aplique instantáneamente a toda la plataforma.
 * RELATED FILES:
 * - JS Engine: /public/assets/js/cpq_engine.js
 * - Partial HTML: /public/templates/partials/cpq_modal_propuesta.php
 * - Blocks PHP: /public/templates/blocks/pricing_*.php
