July 2025 – Highcharts/highcharts: Delivered targeted UI polish for the minimal HTML dashboard demo to ensure dark mode compatibility. Addressed a display issue in the demo title by adjusting CSS for h1#title (padding and background) so the title remains visible and well-formatted under dark themes. This work reduces visual inconsistencies across themes and improves demo reliability for customers evaluating the product.
