/* ═══════════════════════════════════════════════════════════════════════════
   Desktop side rails (≥1200px only): left action rail + right "on this page" TOC
   Built at runtime by blog.js (progressive enhancement). They are position:fixed
   in the side gutters of the centred 720px column — NOT sticky, because #landing/
   body/html all carry overflow-x:hidden, which forces overflow-y:auto and turns
   them into scroll containers that break position:sticky (same reason .lp-nav is
   fixed). The column stays 720px centred so viewport-relative math places the
   rails without ever shifting the text or adding a horizontal scrollbar. blog.js
   fades them in past the hero and out near the footer. Below 1200px: display:none
   — completely absent.
   The 720px column is centred, so the article content box (676px) is centred on
   the viewport middle: its edges sit at 50% ∓ 338px.
