* fix(a11y): use position absolute for skip-next-section link to prevent blank page
* fix(a11y): nest next-section skip link inside last content element
position:absolute alone does not fix the blank-page bug: a full-page
illustration wrapper commonly carries `column-break-after: always`, and
the skip link's static position after that break still renders in a
fresh, blank column. Nest the link inside the deepest last content
element so it shares the final content column, while remaining the last
node in document order for NVDA's virtual cursor. Also use left:auto so
it keeps its static position instead of pinning to the viewport edge.
