/* Full-bleed: the photo's right edge extends past the container to the
   actual browser viewport edge, breaking the site's usual centered-container
   pattern for this one element. calc() cancels out both the container's
   own centering gap ((100vw - 1180px)/2) and its 24px right padding, in
   one negative right-margin. Desktop only (min-width media query below) -
   on mobile the hero stacks into a single centered column (see the 980px
   breakpoint further down), where this breakout would misalign the whole
   layout instead of looking intentional.

   IMPORTANT: this block must stay AFTER the base .hero-story-frame rule
   above, not before it - both set aspect-ratio at equal specificity, so
   whichever appears LAST in the file wins whenever both apply (which is
   always, once the viewport is >= 981px). This exact ordering mistake
   shipped once already: the override sat above the base rule, so the
   base rule's 3/2.1 silently always won and this 3/2.5 never applied,
   even though it looked correct in isolated testing at the intended
   ratio - only caught by checking the real page's *computed* aspect
   ratio, which is why that check is worth doing again if this value
   is ever changed. */
