CRITICAL: Deprecated Sass lighten() function causing build warnings in community.scss

Hey everyone,

I noticed that every time the dev server starts, the build output throws
this deprecation warning:

DEPRECATION WARNING [color-functions]: lighten() is deprecated.
Suggestions:
color.scale($color, $lightness: 30%)
color.adjust($color, $lightness: 30%)

This is coming from community.scss line 105 where lighten(black, 30%)
is used. The lighten() function is being removed entirely in Dart Sass
3.0.0, which means this will break the build when that version drops.

I've put together a fix in PR #3558—it's a small two-line change that
adds the sass:color module and replaces lighten() it with the modern color.adjust()` equivalent. The community page looks and works exactly
the same after the fix.

Worth noting there are similar `@import "deprecation warnings across
several other scss files too—happy to work on those as a follow-up if
That would be helpful.

Cheers!

Esamina community.scss intorno alla riga 105 e la PR #3558 esistente, che contiene la correzione segnalata. Verifica che l’avviso di deprecazione sia stato risolto e che la pagina della community abbia ancora l’aspetto e il funzionamento descritti.
