/* ──────────────────────────────────────────────────────────────────────────
   Insights module — "engineering dossier" editorial styling.
   Loaded only on /insights/ pages (and localized /<lang>/insights/ copies)
   in addition to main.css. Built on the site's navy + machinery-gold tokens;
   adds a monospace label voice (IBM Plex Mono) for a field-guide character.

   Layout principle: ONE reading column (--measure). The feature header band
   is full-bleed navy, but its inner content and the article body share the
   same centered measure, so the H1 and the body text line up on one left
   edge — the thing that made the first pass feel "off".
