/* ==========================================================================
   HERO — dark, full-bleed, corner-anchored.
   Reference points: Spotify / SoundCloud / DJI. All three hold a dark image
   full-bleed and let the type sit small in a corner rather than centered, so
   the photograph does the talking and the words only orient you.

   The backdrop is the client's own photo — DJ Klitchko at the controller
   mid-event. It gets a mild unsharp pass in tools/prep-photos.mjs because a
   1290px source upscales past 1:1 on wide displays.
