/* TradeSafe components.
 *
 * Ordering: chrome, surfaces, buttons, forms, trust, feedback, content.
 *
 * Two rules run through the whole file:
 *
 *  · Glass is structural, not decorative. It marks a layer that floats above
 *    the page — top bar, tab bar, modal, dropdown, sticky status card — so a
 *    reader can tell at a glance what is content and what is chrome. Nothing
 *    that sits *in* the page flow is translucent.
 *
 *  · Motion never moves more than a few pixels and never bounces. This is a
 *    payments interface: the feedback should read as "acknowledged", which is
 *    a small precise movement, not "look at me", which is a large one.
