/* ===========================================================================
   Presently
   ---------------------------------------------------------------------------
   Palette is taken straight off the logo: deep teal for structure, the coral
   spark and amber dashes for the one thing this app is really about — the
   stuff the recipient isn't allowed to see.

   The signature element is .veil: every band of content hidden from the person
   whose list you're looking at sits inside a coral-ruled, faintly hatched
   block labelled with exactly who can't see it. Everything else stays quiet so
   that band reads at a glance on a phone in a shop.

   Type: system sans for the interface, a warm serif for names, and monospace
   for money and states so the buying ledger reads like a ledger.
