/* ===== REVEAL ANIM =====
   Subtle one-shot rise. The keyframe NEVER touches opacity (content stays fully
   opaque at all times), so even if the animation never runs — failed hydration,
   a zero-height/headless viewport, reduced-motion — the content is always
   visible. The only thing that can "fail" is the 14px slide, which is invisible
   to the eye. This is deliberate: content visibility must never depend on JS,
   the IntersectionObserver, or the animation actually ticking. */
