 * Small "i" badge in the image's corner that reveals a stylized hover popover

 * attribute on the <img> itself (accessibility / no-CSS fallback) — but the
 * popover itself is anchored to this small badge rather than the whole
 * figure, because comic images here are tall (portrait) and a popover
 * anchored to the full figure would render far above the viewport instead of
 * near the cursor. Generated content (`attr()`) can only read attributes off
 * the element it's attached to, so the text is duplicated onto this badge's
