/*
==========================================
   NETLIFE SITE — "light in the fibre"
   One idea everywhere: the logo's hexagon and circuit traces, and light
   that travels through glass. Dark ink, one accent: the logo blue.
   Shared by every public page (index, tariffs, tv, ai-assistants, hosting, contacts).
   Old pages (ai-*, cabinet, about) still use styles.css.
