/*
 * ---------- AOS reliability net ----------
 * aos.css hides every [data-aos^="fade"] element (opacity: 0) purely
 * because the attribute exists in the HTML — with no dependency on its
 * JS ever running. If aos.js fails to load or errors out (network
 * hiccup, a blocked script, JS disabled), that content would stay
 * invisible forever. AOS.init() stamps data-aos-easing onto <body> the
 * moment it actually runs, so we use that as the real gate: content is
 * visible by default, and the hide-then-reveal treatment only kicks in
 * once AOS has genuinely initialised.
