/* Logos bridge deposit, a page of the Names Wallet site (nameswallet.app/bridge/).

   Colours, type and radius come from the site's /assets/tokens.css, linked before this file:
   --paper --card --ink --dim --line --orange --orange-text --warn --warn-bg --bad --radius
   --font --font-head. This file defines no colour of its own and never uses --green or --ok.
   Ink for text and titles; one accent, orange: the primary button (ink text on it), the
   current state, link underlines and focus (--orange-text, which holds 3:1 and more on paper).
   --warn/--warn-bg and --bad only for real cautions and errors.

   The header and footer repeat the site's own (site.css: .top .wrap .brand .nav .foot), so
   the bridge sits inside Names Wallet without loading the site's stylesheet. */
