/* =====================================================================
   Hero visual / video poster — compositing strategy
   =====================================================================
   The previous pass switched from `box-shadow` (rectangular outline) to
   `filter: drop-shadow` (follows PNG alpha). That removed CSS-side
   framing, but the monitor still read as a hard rectangle floating on
   the page because nothing in the scene overlapped its edges.

   This pass adds a foreground cloud band — a pseudo-element on the
   right-column wrapper (.pb-hero__visual) that samples the same
   CosmicBackground.png used as the page background, blurs it, and masks
   it from opaque-at-bottom to transparent-at-top. That cloud band sits
   in front of the monitor's lower edge, dissolving the rectangular
   silhouette into the cosmic scene.

   Why a CSS pseudo-element rather than a second <img>:
   - zero extra HTTP requests — the asset is already loaded for body bg
   - color and texture match the scene exactly by construction
   - no DOM noise

   Layering top to bottom: play badge (z 3) > fog (z 2) > monitor (z 1).
   The fog uses pointer-events: none so the entire poster stays clickable.

   FAILURE MODE TO WATCH FOR:
   If the upper portion of the poster (above the fog band) still shows a
   clearly demarcated rectangle against the cosmic background, then
   RightSide.png itself contains opaque pixels around the monitor on its
   canvas. CSS cannot strip pixels out of an image — re-export the PNG
   with a transparent canvas around the monitor and the page will
   compose correctly with no further changes.
