/* ==========================================================================
   Soligo — v2, "Plates & Readings"
   Image-led, not paper-led. The page alternates full-bleed cinematic plates
   (one italic line, nothing else) with quiet narrow readings. Bodoni Moda
   italic carries every display line; a neutral grotesque carries everything
   else at small sizes in short measures. One accent, spent only on the ask.
   Calibrated against wraxalls.co.uk/green-roofing-guide (measured, not eyeballed).
