App UI mockup for a marketing site

Clean product UI screenshot mockup of a {{type of app}} dashboard, shown straight-on with no device frame. Layout: slim left sidebar with icon-only navigation, top bar with a search field, main area with one large primary chart, three compact metric cards above it, and a data table below. Light theme, near-white background, one accent colour {{hex}} used only on the primary action and the chart line. 8px grid spacing, generous white space, subtle 1px borders, very soft elevation on cards. Modern geometric sans-serif type at realistic UI sizes. Text should read as plausible dashboard labels; keep all text short.

Negative: gibberish paragraphs, lorem ipsum blocks, browser chrome, macOS window buttons, drop shadows everywhere, gradients, 3D perspective, neon, dark tech aesthetic.
