   Visuals — hero compositions, glassmorphism, swappable photo slots.
   Real photography is used where a genuinely good match exists (see
   render_photo_slot()/render_hero_background() in includes/functions.php
   and docs/IMAGE-CREDITS.md); every other slot falls back automatically
   to a CSS/SVG geometric composition in the brand palette.
