/*!
 * footer.css — Custom site footer (themes/els-roures/footer.php)
 *
 * Implementa el disseny del handoff de Claude Design ('web-elsroures-com'
 * 2026-05-14), Footer.html. Sistema:
 *  - Paleta càlida (fons cremós #F4F0E8, tinta marró fosc #2A2520)
 *  - Verd corporatiu #5BA740 com a acent (filet superior, botó newsletter,
 *    hover dels enllaços, focus ring)
 *  - Tipografies Lora (serif, només per al wordmark) + Inter (sans, tot
 *    el cos). Carregades per functions.php.
 *  - 4 tiers separats per hairlines (no per fons de color)
 *
 * Ajustos respecte al handoff original (per indicació de l'usuari):
 *  - Els 5 sellos són <img> sense caixa blanca al voltant
 *  - Els 3 logos LEADER sí mantenen caixa blanca (separa l'institucional)
 *  - Les llistes d'enllaços no porten guió "—" davant de cada item
 *  - El filet superior del footer és verd corporatiu (no gris)
 *  - Els logos de "Marca família" no porten cor decoratiu; s'usa el logo real
