Add a Parallax Hero Banner

Add a parallax hero banner section to my [PAGE_NAME] page. Use the image [IMAGE_URL] as a fixed background that creates a parallax scrolling effect. Set the section height to [HEIGHT] pixels. Center the heading [HEADLINE_TEXT] vertically and horizontally in [HEADING_COLOR] color with a text shadow for readability. Below the heading, add the subtext [SUBHEADLINE_TEXT]. Include a CTA button labeled [CTA_TEXT] linking to [CTA_URL] with rounded corners. Add a color overlay using [OVERLAY_COLOR] at [OVERLAY_OPACITY] percent opacity. The parallax scroll speed should feel smooth and subtle. On mobile devices, disable the parallax effect and show the image as a static background.
