The sidebar occupies the left gutter, the right gutter balances it; wide screens get columns inside long articles without changing the article's width. Columns are decided client-side (pagerite.js): the body splits into segments at h1/h2 headings and `.wide` elements (full-width separators, never inside columns), and a segment gets columns only when it holds enough text — code blocks are excluded from that measure, and a `::: nocols` container opts its whole section out.
