/*
 * The design system.
 *
 * Frosted white glass floating over a pale, softly lit field. Calm and
 * financial, not neon crypto. One typeface throughout, separated by weight and
 * tracking rather than by a second family. Nothing shouts: the only solid,
 * saturated object on a page is the primary button.
 *
 * Two rules do most of the work, and both are here rather than in a comment on
 * a component:
 *
 *   - Shadows are tinted blue, never grey. Blue is the colour of what is behind
 *     the glass, and a grey shadow makes the same surface look like paper.
 *   - Buttons are never pills. A rounded rectangle says this holds numbers and
 *     decisions; a pill says toy.
 *
 * The one idea the product needs on top of that: every surface says which half
 * of the protocol it belongs to. Public is indigo, private is lavender, and the
 * word is on the surface as well as the colour, so it survives greyscale.
 */
