   ASSICOMUNALE — Footer Enterprise
   Version: 3.1.0 (was 3.0.0)
   Components: Pre-footer CTA + Main Footer + Bottom Bar

   Wave 6 E1 fixes applied by: frontend-builder
   skills-loaded: harden, audit, polish, optimize, clarify
   principles-cited:
     - harden §"minimum contrast for legal text" → IVASS disclaimer 2.64:1 →
       ~9.4:1 (rgba 0.70 su dark purple), copyright 3.66:1 → 10.5:1 (rgba 0.75)
     - adapt §"touch targets 44x44 min on touch devices" → footer links
       min-height 24px desktop, 44px mobile
     - polish §"Link-in-text-block WCAG 1.4.1" → footer links underline
       default + stronger on hover
   resolves: P0.3 IVASS contrast, copyright contrast fail,
             P1 a11y.3 touch targets footer links, P1 a11y.4 underline
             (refs Wave 5 D1 a11y audit)
