      meglio uno scroll orizzontale del contenitore che non un clipping.

/* \u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500 PATCH-LUCA map-transition: crossfade colori esagoni \u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500
   Obiettivo: quando l\u0027utente cambia categoria, gradient mode o steps mode,
   gli esagoni della mappa NON devono cambiare colore di scatto, ma fare un
   crossfade morbido (\u0022i vecchi colori si spengono, i nuovi si accendono\u0022).

   Come funziona:
   - Leaflet renderizza ogni esagono come elemento SVG \u003Cpath\u003E dentro
     .leaflet-overlay-pane (renderer SVG di default).
   - Quando chiamiamo geojsonLayer.setStyle(...) (cosa fatta da refreshMapColors()),
     Leaflet aggiorna gli attributi \u0022fill\u0022, \u0022fill-opacity\u0022, \u0022stroke\u0022, \u0022stroke-opacity\u0022.
   - Mettendo una transition CSS su questi attributi, il browser anima
     automaticamente il passaggio tra il colore vecchio e quello nuovo.
   - Niente modifiche al JS: vale per cambio categoria, steps 10/15, gradient on/off,
     opacity slider \u2014 tutto quello che passa per setStyle().

   Durata 0.45s = leggermente piu\u0027 lunga dei pulsanti category (0.28s) perche\u0027
   la mappa ha tanti elementi: serve un po\u0027 di tempo in piu\u0027 per percepire
   l\u0027onda di cambiamento, ma resta veloce e mai \u0022pesante\u0022.

   Easing cubic-bezier(0.4, 0, 0.2, 1) = stessa curva dei pulsanti category,
   per coerenza percettiva (Material Design \u0022standard\u0022). */
#map .leaflet-overlay-pane svg path {

    stroke-opacity 0.45s cubic-bezier(0.4, 0, 0.2, 1);
}

/* Durante pan/zoom Leaflet ricalcola i path: disabilitiamo la transition in
   quei frame con la classe .leaflet-zoom-anim (gia\u0027 messa da Leaflet) e
   anche quando trasciniamo, cosi\u0027 il movimento mappa resta nitido e fluido
