/* order-flow.css — channel-order page styles.
   Page-specific layer for the consumer "Open a Lightning channel" flow. Loaded AFTER flow-ui.css, which
   supplies the design tokens (:root), base resets, and shared chrome (.shell / .top / .brand / .mark /
   .sub / .tabs / .spacer). Only the rules unique to this flow live here, mirroring how swap-flow.css sits
   on top of flow-ui.css for the swap page. Extracted verbatim from the old inline <style> in
   channel-order-flow.html when that page was ported to the Scala.js `web` app. */
