[Colors] deep violet #2B1B5A header fading to lavender #6B4FA8, clean white #FFFFFF middle, purple-to-orange gradient footer. [Layout] the top 22 percent is a full-bleed title band; the middle 55 percent stays empty white negative space for a host and product; the bottom 23 percent is a benefit strip with three outlined icon-and-label columns and a haunted rock island bleeding off the right edge. [Typography] brushed gold "HALLOWEEN SPOOKY NIGHT" with hairline rules and bat dividers, small white sans labels beneath each icon.
