   FIX: dark sliver / line across the very top of every hero.
   The header is now position:fixed (out of flow, see the rule
   above), so heroes must NOT be pulled up with a negative margin
   anymore — they start at the very top of the page and fill the
   whole area behind the transparent header. Each hero's own
   top padding (>=120px) keeps content clear of the header.
   This overrides the older -80px pull-up rule above.
   Delete this block + the position:fixed lines to revert.
