  /* ===========================================================
     ARTICLE page

     Article pages share the global ``--max-content: 1400px`` cap with
     the homepage hero/grid, but at that width the 220px sticky TOC
     drifts to the far right of the screen while the prose column —
     constrained to 72ch / ≈609px — leaves a ~500px dead zone in the
     middle on a typical 1440px laptop. We override the outer cap with
     a tighter ``--max-article`` and let the prose use a more generous
     bilingual reading width (~86ch) so that the main column actually
     fills its grid cell next to the TOC.
