/* vllm-ui — "bench instrument" design system.
 *
 * One RTX 5090, one model, one 32 GB budget: the UI reads like the front
 * panel of a lab instrument. Graphite ground with a faint phosphor cast,
 * amber as the single interactive accent (hardware-LED amber — never used
 * for status), reserved status colors that always ship with an LED square
 * + text label (never color alone). Mono-led type from system stacks only:
 * deployments may sit on an isolated VPN, so no webfonts.
 * Signature: the VRAM strip under the header — the 32 GB line everything
 * in this repo is fitted into, on screen at all times.
