   site_header.css — cabecera, drawer, footer y botón de WhatsApp
   ------------------------------------------------------------
   Markup: components/site_header.php y components/site_footer.php.
   Tokens: base.css (bloque «Solumed»). Medidas de la cabecera:

     ancho        topbar  nav  logo  total │ scrolled
     ≥1200          36     84   52    120  │ topbar oculta, nav 68, logo 42
     1024–1199       0     76   46     76  │ 64 / 38
     601–1023        0     72   44     72  │ 64 / 38
     ≤600            0     64   36     64  │ 60 / 34

   El logo es turquesa sobre transparente: la cabecera es petróleo en
   todos sus estados.
   Estados:
     sin JS           sticky, fondo petróleo
     .js              fixed; body.no-hero reserva var(--sh-total) arriba
     .js .has-hero    transparente sobre la foto
     .is-scrolled     topbar fuera (translateY), nav compacta, petróleo .9 + blur
   Las variables --hd-* resuelven el color de cada estado en un solo lugar.
