Replace float+padding-left approach (which narrowed article text) with
position:absolute on each sidenote, placing it to the right of 100% of
.e-content so it paints in the existing left page margin. Text width is
unchanged. Requires viewport ≥ 1440px where the margin is 224px (210px
needed). JS sets each sidenote's top relative to its reference span via
getBoundingClientRect, with 8px overlap prevention.
