  Make header vertical instead of squeezed
  .header-row {
    flex-direction: column;
    align-items: flex-start;
    gap: 1rem;
  }

  Navigation: stack links + bigger tap targets

    gap: 0.5rem;
  }

  nav a {
    padding: 0.8rem 0;

  Improve margin/padding on small screens
  header {
    margin-bottom: 2rem;
    padding: 1rem 0;
  }

  .column {
    padding-inline: 1rem;

  Ensure text remains readable on small screens
  body {
    font-size: var(--fs-300);
    line-height: 1.5;
  }

  Prevent long justified text rivers on narrow screens
  p {
    text-align: left;
  }

  Footer: center everything
  footer {
    flex-direction: column;
    gap: 0.5rem;
  }
