/* Home page - hero banner and section effects (2026-10-03).
   Hero layers, bottom to top: ::after = the theme picture (inherited from .hero-section, so it shows without JS) with a slow
   drift > ::before = shade for readable text + fade into the page > home-fx.js layers (canvas, sky flash, sheen) > text.
   On wide screens the banner is always full width and takes the picture's own shape (--hfx-ratio = width / height, set by
   the view) up to 78 % of the window height, so the whole artwork shows instead of a thin cropped strip; the text then
   sits on the left. Phones keep the centred layout.
   .hfx-art is only set when the picture file exists, so without one the banner keeps its old text-sized layout.
   Decoration only: pointer-events none, aria-hidden; prefers-reduced-motion keeps everything still. */
