Post Header Image Front Matter
A short example post showing how headerImage replaces the default aero waves background in a post header.
This post exists to demonstrate the headerImage front matter option. When the value points to an image shipped inside the post bundle, the post header uses that image instead of the default aero waves.

The theme fingerprints the image through Hugo resources. The header still uses the same top-to-bottom fade behavior as the aero waves, with the custom image blended at 50% opacity.
Fallback behavior
Posts without headerImage keep the default aero waves header. That means existing posts do not need to be updated just because the feature exists.
Bundled artwork
Keeping one-off post artwork inside the post directory makes the content portable while still using the same header rendering path.
