   worldrobots.cn - goods detail photo display cap
   Version: 20261113a
   Applies to: every ShopXO goods detail page (PC + H5), every product,
               every product photo - no product id / class / src selectors.

   Problem: a 427x850 portrait product photo was rendered at the full width of
   the description column (928px on a 1440px viewport) because the product
   description ships its own embedded <style> with width:100% and no pixel cap,
   producing a 928x1845 image (~2 screens tall). The PC magnifier gallery was
   already bounded, but had no explicit guard against future theme changes.

   Fix: cap the leading product photo at ~400px wide / 800px tall on all
   viewports. Portrait images keep their aspect ratio (object-fit: contain)
   and never stretch the page. The magnifier (jqzoom) and the thumbnail
   carousel are untouched.

   !important is required for the description image because the embedded
   product-description stylesheet (stored as product content, not editable
   from here) has higher selector specificity than any head stylesheet.

/* 1) PC magnifier gallery: hard ceiling for the photo display box.
      Current theme already yields 400x398, so this is a guard, not a
      restyle - no computed value changes on the live page. */
