/*
 * Boop VPN web design. Built on the ideas of GitLab's Pajamas design system:
 * neutral grays, one blue for actions, Inter type, a 4 px grid, 4 px corners on
 * controls and 8 px on panels, 1 px borders, no shadows, no gradients.
 * Layout rules: every row of tiles is full (see evenCols() in app.js), tiles in a row
 * share one height, controls in a row share one height, edges line up on the container.
