/*
 * The web client's design foundation (VAI-031, ADR-021).
 *
 * Material Design 3's structure — tonal surface roles, a shape scale, state
 * layers, a type scale — expressed in the palette and density of the
 * VNCdirectory org-console prototype, so the two products look like one suite.
 * Not the material-web component library: a custom-element bundle would fight
 * Turbo's morphing and the platform's CSP, and M3 is a system before it is a
 * package.
 *
 * Tokens are named for their role, never their colour, which is what lets the
 * dark scheme be a token swap rather than a second stylesheet.
