/*
 * The platform's one hand-written stylesheet (ADR-005: no CSS framework, no build step), in the
 * look of the approved design prototype (PD-077; docs/03-architecture/design/).
 *
 * Mobile-first: the unqualified rules are the phone layout, held at the till; one min-width query
 * widens it on larger screens. Black and white with a grey scale. Colour appears only where it
 * means something: green for passed, red for not passed, amber for in progress or due. A colour is
 * never the only carrier of meaning: every badge and result carries its word as well.
 *
 * NFR-05 (WCAG 2.1 AA). Every text and background pair below meets 4.5:1 or more, and every
 * control border 3:1 or more; the pull request states the ratios. Focus is always visible.
 *
 * Class names, after the prototype. Administration pages (lane 52) write their markup against
 * these names; the shell's helpers in ui/Layout.kt write the app bar, trail and back link.
 *
 *   Shell     appbar, wordmark (.dot), lang, who (summary .avatar .t), menu (.id), skip, vh
 *   Way about crumbs (.sep), backrow, back
 *   Headings  h1, h2, lead, eyebrow
 *   Buttons   btn | btn ghost | btn quiet | btn danger, plus block and sm; links and buttons alike
 *   Surfaces  card, hero (.ring), cert (.seal), result (.big ok|bad), callout, notice-*
 *   Status    badge | badge ok | badge bad | badge warn | badge dark
 *   Progress  bar (<i style="width:..">), dots
 *   Lists     list, li (.tick, .tick.done, .grow), mods, mod (.n .tt .row), tiles, tile (.v .l)
 *   Forms     field, label.f, input, help, hint, choice, opt, radio, actions, search
 *   Tables    table.data (or any table in a card)
 *   Actions   sticky (.hint): the bottom action bar on phones
 *   Dialogs   modal (a <dialog>), acts
 *   Test      qhead, step (one question per screen, ui/test.js)
