Lightdash
The open-source BI landing that earns the attention of both engineering leads and design-minded PMs — a page that reads like well-typeset documentation wrapped around a dashboard. Lightdash commits to three unfashionable choices at once: pure black primary ink against an off-white canvas, a small-foundry display face (Britti Sans Variable) paired with Inter Variable as the only typographic voices, and the preserved native #0000ee hyperlink blue as an editorial credibility signal. Elevation runs on a multi-layer soft shadow grammar (up to four stacked layers) that makes cards feel printed rather than floated.
