   1. Entry point — a special "Carbon Story" card that sits in the hero
   row, in the empty half to the RIGHT of the gross-emissions balance
   card (above the KPI grid). walkthrough.js builds it and slots it there;
   `.wt-hero-host` (added to `.hero-row` only while the card is present)
   turns that row into a two-up flex layout so the card fills the gap and
   matches the balance card's height. Background is the entrykct.mp4
   footage; a light spins around the border on hover. No SVG. app.js /
   styles.css are never touched.
