/* wallet.css — layout and components for the RH Chain wallet.
 *
 * Built on the Zoltan token layer (assets/zoltan.css), which owns the identity:
 * CRT phosphor on basement black, mono display type, the glow. This file owns
 * structure only, so the brand can be restyled in one place.
 *
 * ONE DELIBERATE DEPARTURE FROM THE BRAND. rhchain.network leans hard on glow
 * and scanlines because it is a poster. A wallet is a place where people read
 * numbers that decide whether they have been robbed, so here the effects are
 * dialled back and contrast is dialled up: body copy is chrome, never phosphor
 * on a glow; amounts are mono and large; destructive things are the only red on
 * the screen. The identity survives in the palette and the type, not in the
 * bloom.
 *
 * Everything is sized for a phone first — this ships as an Android app around
 * the same markup — and widens to a single centred column on a desktop. There
 * is no wide layout, because a wallet has one thing to say at a time.
