/* ── SCROLL CONTAINER ────────────────────────────────────────
   The AffairOva ao-note-header is position:sticky at top:0.
   Any content_html that uses position:sticky internally would
   stick relative to the VIEWPORT, overlapping our header.

   Fix: lock body height to viewport, put all content in a
   fixed scroll container that starts below the header.
   Sticky elements inside content_html now stick relative to
   THIS container — they can never escape above it.

   ao-header heights from header.css: 56px mobile, 62px desktop.
