/* ============================================================
   hover-info.css — rosovo.org inline popover component
   ============================================================

   USAGE — wrap any phrase in a <span> with class="hover-info":

   <span class="hover-info"
     data-title    = "Card heading"
     data-desc     = "One or two sentences shown under the title."
     data-link     = "https://example.com"
     data-link-label = "Read more"
     data-img      = "images/optional-image.jpg">
     your highlighted phrase
   </span>

   ATTRIBUTES
     data-title       required   heading shown in the card
     data-desc        required   short description text
     data-link        optional   URL for the "learn more" link
    data-link-label  optional   link text (defaults to "Learn more ->")
     data-img         optional   path/URL to image or gif (omit for text-only card)

   BEHAVIOR
     hover  — card appears above the phrase (flips below if near top of viewport)
     click  — locks the card open; X button or clicking outside dismisses it
