/* ----- Inner-page hero duotone (.page-head.has-bg) ---------------------------
   Brings inner-page heros into the same navy↔sage duotone family as the
   homepage .hero. Each page sets its photo + a navy scrim gradient INLINE
   (per-page image), so the treatment can't be rebuilt on a pseudo-element
   without editing HTML. Instead two pseudo-elements blend with the element's
   already-painted background:
     ::before → navy→sage duotone, mix-blend-mode:color  (maps photo into palette)
     ::after  → bottom legibility scrim + faint gold wash
   Text lives in .container (z-index:2), painted above both overlays → stays crisp.
   Scoped to .has-bg, so the plain navy .page-head (no photo) is untouched.
   SEO article hero headers share this class and are treated too (intended, per
   the photography guide). Prose images (.prose img) are NOT affected. */
