/* =============================================================================
   product.css — CAPA 3 de 3: LAYOUT DE LA FICHA DE PRODUCTO (PDP)
   Solo secciones de esta página. Carga después de base.css y shop.css.
   -----------------------------------------------------------------------------
   INVARIANTE: aquí no se redefine ningún componente de base.css ni de shop.css.
   Se comprueba con:
     grep -nE '^\.(btn|nav|topbar|iconbtn|tools|logo|sucrow|sacts|pcard|chip-f|
                    ann|sucwrap|sucdrop|foot|scrim|cart|cmdk|news|cofstrip|prods)\b' product.css
   Debe devolver cero líneas. Tampoco se toca el reset de elemento (*, html, body,
   a, img, h1-h4, section): las secciones nuevas usan `.pdp-section` para el
   borde/ritmo en vez de reabrir el selector `section`.
