An app window * with a sidebar (team switcher, sections, projects, the month's usage) and a main column: the * breadcrumbs, search and notifications; the project's title with its environment and address, * the time range, a region filter and Deploy; four KPIs with bar sparklines; traffic by region on * a dotted world map; the regions with an alert and their latency; the latency chart; and the * latest deployments. * * - Live: while the screen is on show, requests travel the map's routes, and every 1.6 s the *   regions' traffic, the total and the newest request bar move a little. * - Map: hovering or focusing a region opens its popover (p95 over the last hours, p95, requests, *   errors); clicking one filters the screen to it, as the region menu does. * - The alert: Shift 30% to hkg1 moves traffic over two seconds: sin1's latency, its dot on the *   map, its row, the KPI and the chart come back down, and a route from sin1 to hkg1 appears. *   Undo moves it back. Open trace shows the slow request's spans. * - 1h / 24h / 7d / 30d change the KPIs and the chart; the legend hides or shows each line; *   deploy markers on the chart are buttons. Search filters the regions and deployments. *   Deploy adds a deployment that builds, then goes live. * - Layout from its own width (container queries): the reference's two columns from 1400 px, *   one column of cards below; the sidebar is an icon rail under 1100 px and a drawer under

Everything is laid out on a 749 × 315 board, which is * scaled to fit the card (never above its own size) and centred: * * - the land is a grid of dots on a canvas drawn at the device's pixel ratio. A dot's shade comes *   from how close it is to a region (weighted by that region's traffic), with a little steady *   noise, and dots around an elevated region turn red.

They stop *   when the root says the screen is paused (offscreen, hidden tab, reduced motion). * - each region is a button: a dot with its halo and a label with its code and traffic. Hovering *   or focusing one opens the popover beside it, with its p95 over the last hours and its stats; *   leaving the map brings back the pinned region (the elevated one), if there is one. */import { useEffect, useLayoutEffect, useRef, useState, type CSSProperties } from 'react';import {  ARCS,  MAP_H,

Sizes are the screen's own px, measured on the reference at its true scale (the window is   1445 × 903 there). The layout follows the component's own width (container queries on the   root): two columns of cards from 1400 px, one below; the sidebar is an icon rail under 1100 px   and a drawer under 720 px.   Colours are the tokens below, light-dark(light, dark) where the two differ: the component takes   the color-scheme it inherits from the page (light unless the page says otherwise), or the one   its colorScheme prop sets (data-color-scheme).   Motion is transforms and opacity: the requests on the map ride an offset-path, the bars grow   by scaleY, the meters by scaleX. All of it pauses with data-paused on the root (offscreen,   hidden tab, reduced motion). */.root {  --sans: Inter, ui-sans-serif, system-ui, -apple-system, 'Segoe UI', sans-serif;  --mono: JetBrains, 'JetBrains Mono', ui-monospace, 'SF Mono', Menlo, Consolas, monospace;  --page: #ececee;  --frame: #fbfbfc;  --frame-edge: #dcdce0;  --rule: #e6e6ea;  --card-top: #ffffff;
