/*
 * Design tokens: a soft neutral canvas with faint colour glows, floating
 * frosted-glass bars made of grey groups, white rounded cards with long soft
 * shadows, thin grey line icons and a blue accent used sparingly (selection,
 * sliders, focus). See ROADMAP.md, "Дизайн-система".
 *
 * Everything is measured on a few scales, never in between:
 * - space: a 4px grid (4 8 12 16 20 24 32 40 48 64 80);
 * - radius: 6 10 14 20 28 and pills; a shape inside another shares its
 *   centre, so an inner radius is the outer one less the padding between;
 * - type: 11 12 13 14 16 20 28 and the hero; tracking tightens as type grows;
 * - heights: 30 small controls, 36 controls, 44 fields, 54 bars.
