/*
 * iFairy Curriculum — shared design system (2026-10-04).
 *
 * One stylesheet for every public page (was ~200 lines of near-identical
 * inline CSS in each of 8 templates). Light by default — schools print pages
 * and project them on classroom boards — with a dark theme that follows the
 * OS setting or the header toggle (<html data-theme>). The iFairy identity
 * stays: blue→violet brand mark and hero gradient, rounded cards, friendly
 * type; it is deliberately not a GOV.UK look-alike (we are independent).
 *
 * Accessibility (WCAG 2.2 AA): text colours are ≥ 4.5:1 on their surfaces in
 * both themes, a visible :focus-visible ring everywhere, skip link, reduced
 * motion honoured, print styles strip the chrome.
