/* =====================================================================
   SIGNAL — Data Scientist Portfolio Template
   Plain HTML5 + CSS3. No frameworks. No build step.
   ---------------------------------------------------------------------
   Clean, technical aesthetic: dark navy surfaces, a teal accent, light
   text, tidy metric cards and monospace accents. Project covers and
   charts are real images (picsum) and people are avatars (pravatar).

   REBRAND TIP: edit the CSS variables in :root below. Swap --accent for
   your primary color and update --font-head / --font-body / --font-mono
   plus the Google Fonts <link> in each HTML file. Everything else cascades.
