/* Footer unico dei siti SPUN (packages/site-kit, D-043): uguale su spun.ai e su ogni sito prodotto.
   Generato da site_kit.footer_html(); sul modello di spun.tel (DESIGN_SYSTEM §10 e §15).
   Variabili proprie con ripiego: i token di spun.ai (--sx-*) o le variabili delle landing (--bg, --text, --rule…),
   così lo stesso file funziona ovunque senza toccare il CSS del sito.
   Ogni regola parte da .sx-footer e il logo e le icone hanno classi proprie (niente .sx-logo o .sx-px):
   così le regole generiche dei siti (per esempio .sx-chat .sx-px) non entrano nel footer. */
