/* CP Tech fleet platform — design system.
 *
 * One hand-written stylesheet, served as a file rather than inlined into every
 * page: the browser caches it once, and there is exactly one place to change a
 * colour. No build step, no framework — consistent with the rest of the stack.
 *
 * Dark only, deliberately. A second scheme means every colour, border and state
 * has to be checked twice, and the public driver forms will get their own light
 * appearance anyway.
 *
 * Palette derives from the brand assets: #1f1d21 (dark) and #59c2dc (cyan) are
 * taken from the logo SVG, everything else is built around them.
