 * Footer component styles for Barrio Red Aprende
 * Approach 1: Single shell with gradient + pseudo-element side rails + cream card + GOV.CO bar
 *
 * Structure:
 * - Shell with white strip (26px) → education red gradient
 * - Pseudo-element side rails in education red
 * - Cream card with rounded top corners and shadow
 * - Top block: navigation columns + Colombia Aprende logo
 * - Yellow decorative bar
 * - Middle block: institutional info + Educación logo
 * - GOV.CO bottom bar with cobalt background and yellow divider
 *
 * Uses BEM methodology and --ra- CSS custom properties
