/* ==========================================================================
   VLN8N — design system

   A production tool, not a marketing site. The palette follows professional
   audio and video editors — deep blue-grey panels with one cyan accent — so
   long editing sessions stay comfortable and the interface reads as an
   instrument rather than a landing page. Small sharp radii, a real
   typographic scale, no gradients and no decorative glow.

 * looked unfinished, and `.select--inline` was simply inert on every tool
 * screen so an inline dropdown grew to 613px inside a toolbar and gave the
 * strip a scrollbar.
 *
 * Defined here unscoped so the component works wherever it is used. The
 * admin-scoped copies still win on admin screens and say the same thing, so
 * nothing there changes; they are now redundant and can be deleted from
 * admin.css in a quiet moment.
