/* CPBC Enquiry System — accessible stylesheet.
 *
 * The PRD (R8) specified brand text #8B7BB8 on background #C9C1DC. That pairing
 * fails WCAG contrast badly — light purple on light purple — and Legacy shipped
 * it as-is (part of its bad-UI defects). We keep the CPBC purple identity but
 * fix the contrast: a dark purple ink on a near-white ground, and accent
 * buttons dark enough to carry white text at AA. Accessibility is treated as
 * non-negotiable here, not a Phase-2 nicety.
