/* ---- Hero crossfade ----------------------------------------------------
   Two stacked layers, one CSS animation, zero JavaScript. CSP stays at
   default-src 'none'.

   The scrim is a horizontal gradient, not a flat wash. Text is left-aligned,
   so the darkness sits on the left and the photograph breathes on the right.
   hero-1 contains a blown-out window that reaches pure white directly behind
   the headline, so every stop below is verified against rgb(255,255,255):

       x=0%    alpha .88   white 11.54:1   sage 8.39:1
       x=35%   alpha .86   white 10.81:1   sage 7.86:1
       x=55%   alpha .82   white  9.39:1   sage 6.83:1
       x=60%   alpha .75   white  7.19:1   sage 5.23:1   <- text ends here
       beyond  ------------ no text, photo shows through

   On narrow screens the text spans the full width, so the gradient flattens.
   Missing images degrade to the plain ink hero: the slides go transparent and
   ink-over-ink composites to ink.
