/*
 * Board Result Checker — embeddable widget styles
 *
 * Design language: "Result Ledger".
 * Where a full-page result portal can afford atmosphere, an embedded widget
 * cannot: it sits inside somebody else's article, between their paragraphs, in
 * their typography. So this reads as a precise instrument rather than a hero —
 * a bordered ledger card with a coloured spine, tabular figures, and a
 * before/after column rule that makes the change legible at a glance.
 *
 * Two rules hold the whole file together:
 *   1. Every selector is scoped under .brc-root. Nothing is written at document
 *      level, so the widget can never restyle the host theme.
 *   2. Every property the host theme might have set on a shared element is
 *      reset explicitly. A theme's `button { text-transform: uppercase }` must
 *      not leak in.

 *
 * Themes routinely style bare `button`, `input`, `select`, `label` and `svg`
 * — and a surprising number do it with !important. A plain reset loses to
 * that, so the properties a theme can realistically hijack are re-declared
 * here with !important too. Our selectors are more specific than a bare
 * element selector, so when both sides are !important we win.
 *
 * This is deliberately limited to hijack-prone properties. Anything the
 * widget varies internally (accent colours, state backgrounds) is left to
 * the normal cascade.
