/*
 * Tech9IQ UI kit — the look of the AWS module (Tech9IQ/aws_observability, main),
 * rebuilt in plain CSS so the Ops Console, Customer-Login and Billing share it.
 * The same file lives in each of those repos; change it in all three.
 *
 * Values are the AWS module's own (its tailwind.config.js brand/semantic scales
 * plus Tailwind's slate), with its known inconsistencies fixed rather than copied:
 * one input style, one focus ring, header and top bar the same height, success
 * notices with a green border, light chart colours.
 *
 * Icons: /assets/icons.svg (lucide 0.446), used as
 *   <svg class="i"><use href="/assets/icons.svg#i-server"/></svg>
