/* ── Article layout: reading column + side rail ─────────────────
   Only pages that have a rail (articles: Key Takeaways + "Concepts in this
   article"); concept and podcast pages keep the plain 720px column.
   - Below 1200px: one column, as it always was. Key Takeaways stay above the
     image, collapsed. The Concepts block shows its "end" copy (after the
     article, before the credits), so nothing sits between the title and the
     image except the takeaways bar.
   - From 1200px: the text column stays at ~70 characters per line (wider
     would be harder to read). The title block keeps the text column only, and
     the rail starts at the top of the image (grid row 2): the eye reads
     title, deck and reading time first, then finds the margin notes. The rail
     moves with the article (not sticky, no inner scroll bar). Key Takeaways
     are open by default (the small script at the end of the page opens/closes
     them when the window crosses 1200px); the "rail" copy of the Concepts
     block shows under them. */
