/* ==========================================================================
   analytics.js: visitor statistics for somabhatta.github.io

   Uses Umami (cloud.umami.is), which shows visitors by country / region /
   city and records the click events below. It sets no cookies and stores no
   personal data, so no cookie banner or consent click is needed.

   SETUP: paste your Umami Website ID below (empty = tracking switched off).
