Five PNGs at app/static/images/ (renamed from screenshot dumps):
- dashboard.png — full dashboard hero shot, sits below the hero CTAs
- news-feed.png — feature-card thumbnail: auto-tagged news feed
- indicators-read.png — feature-card thumbnail: per-group AI commentary
- strategic-log.png — feature-card thumbnail: hourly strategic log text
- chat-with-log.png — "More views" gallery: ask follow-ups against a log
Every screenshot is a <button class="shot"> with data-full + data-caption;
click opens an HTML5 <dialog>-based lightbox. <dialog> handles focus trap,
ESC-to-close, inert background; the backdrop click closes too. Images use
loading="lazy" so the lightbox-only ones don't block first paint.
CSS appended to cassandra.css: .shot, .shot-hero, .shots-grid, .shot__caption,
and .shot-modal (+ ::backdrop). All colours pull from the existing palette
vars so light and dark themes stay coherent.
Total image weight: ~950 KB across all five — acceptable for a marketing
landing page with lazy-loaded thumbnails.
