/* The background-upload dock — the one thing on screen that outlives the page.
 *
 * Written as plain CSS, not Tailwind utilities, for the same reason
 * order_tracks.css is: this component is injected by JavaScript on every route
 * of the app, so it cannot depend on utility classes surviving a template it
 * was never written into. It also has to be legible over whatever page happens
 * to be underneath it, which means owning its own stacking and elevation.
 *
 * Palette follows the app: primary maroon (#7a1526 / #6b1521) for the active
 * bar, emerald for a finished file, amber for one that needs the user, and
 * neutral greys everywhere else. Logical properties (inset-inline-end, padding
 * -inline) throughout, so the dock lands bottom-LEFT in Arabic without a single
 * [dir="rtl"] override.
