/* ── Image sizing override ──────────────────────────────────────────────
   The publisher's scoped CSS sets per-image dimensions via classes
   like `img._idGenObjectAttribute-N { width:…; height:…; min-width:100% }`.
   Pixel-width rules are fine — they reproduce the source figure size.
   But a few rules use percentage-based sizing (intended for the
   InDesign viewer's container) which forces small images to stretch to
   100% of our differently-sized review container, breaking aspect ratio.

   To keep source widths intact while preventing the stretch, we use
   `!important` to force aspect-preserving height and a safety cap on
   width.  Specificity-wise the publisher's `.qa-card ._idGenObjectAttribute-N`
   (0,2,0) would otherwise win over our (0,1,1) override.  `width: auto`
   lets the publisher's explicit `width: 252px` still apply because
   `width:auto` only takes effect when no other `width` is set. */
