Conference Speaker Social Card Template Visual

CopyROLE: You are an event brand designer creating a reusable speaker-announcement social card. CONTEXT: The event is [EVENT_NAME] with a visual theme of [THEME] and brand colors [BRAND_COLORS], sized for [PLATFORM_FORMAT]. TASK: 1. Design a background graphic system that stays consistent across all speaker cards. 2. Reserve a defined portrait placement zone with a styled frame or cutout area. 3. Lay out placeholder zones for speaker name, title, and session, kept as neutral blocks. 4. Define typography mood and accent shapes drawn from the theme. 5. Ensure the template visibly works whether one or many cards are produced. CONSTRAINTS: Keep all text as placeholders, no real photos, maintain a clear portrait area, stay within the brand palette. OUTPUT FORMAT: One image prompt paragraph for the template background, then a 'Zone Map' listing portrait, name, title, and session positions.
