/*
 * Pick A Deal — one stylesheet, no build step.
 *
 * Design notes, because the choices here are not arbitrary:
 *
 * - This is a money app used almost entirely on phones, over patchy mobile
 *   data. So: bottom tab bar rather than a sideways-scrolling header, tap
 *   targets at 44px, tabular figures on every amount, and no web font blocking
 *   first paint.
 * - The brand is jade through cyan. Green because the product is money held in
 *   escrow and green is what trust looks like in that context; the cyan end
 *   keeps it from reading as yet another bank.
 * - Depth comes from layered surfaces and one soft shadow, not from borders
 *   everywhere. Borders are for separation, elevation is for hierarchy.
 * - Dark is the default and the design is drawn for it. Light mode is a real
 *   theme, not an inversion.
