   Base = shared white-card look (background, radius, shadow).
   Per-logo modifier = size + internal padding + baseline align,
   tuned to how much whitespace each source image bakes in.

   Padding summary (padding = extra whitespace inside the white card):
   ┌──────────────┬──────────┬──────────────┬──────────────┐
   │ Modifier     │ Source   │ height  vpad │ hpad  valign │
   ├──────────────┼──────────┼──────────────┼──────────────┤
   │ --sup        │ png/svg  │ 14px    1px  │ 3px   0      │
   │ --cmlab      │ png      │ 22px    2px  │ 4px   -6px   │
   │ --enc        │ png      │ 22px    4px  │ 8px   -6px   │
   │ --cau        │ png      │ 26px    4px  │ 6px   -8px   │

   └──────────────┴──────────┴──────────────┴──────────────┘
   --sup is the tiny marker used inside <sup> after an author's name
   (replacing the numeric affiliation index). Lab wordmarks (--cmlab,
   --enc) sit at 22px on the affiliation line so they don't dominate
   surrounding text; university crests (--cau, --khu) go to 26px.
   The KHU SVG is tightly cropped, so it takes less card padding
   than the CAU PNG which has visible whitespace baked in.
