/*
 * CPD by Roche: brand styling. Brand colours from KADCYLA HCP Brand Style Guide v2 (p4): purple #7e0c6e, gold #f6a11c,
 * accent #5b004e, tertiary #d7646e / #f2eb46 (not used as text). Digital type is Tahoma (p7). No inline styles anywhere (CSP), no webfonts (Tahoma is not licensed for web hosting).
 * Colours: only the values in test/helpers/palette.js. test/a11y.test.js checks this file uses nothing else
 * and that each text/background pair below reaches 4.5:1.
 *   ink #111111 on white / on page   body text, labels
 *   white on black / on purpleDeep   skip link, admin footer, admin header
 *   ink on gold                      buttons (white on gold fails 4.5:1)
 *   error #a40022 on white / page    error text
 *   purple on white / page           links, headings
 *   gold on black                    skip link focus ring
 *   Public side is all light: white panel and question cards on the lilac page, white footer, purple links.
 *   Selected option: purple border on infoBg tint, with the native radio/checkbox still showing the state.
 * Admin dashboard (all rules scoped under .admin): sidebar white on purpleDeep, pills and callouts use the status pairs in palette.js,
 * danger button is white on error red; the palette module lists every pair and test/a11y.test.js checks them.
